Book cover of A Clean Kill in Tokyo

Philippe Espinasse Author Of Hard Underwriting

From my list on thrillers set in Asia.

Why am I passionate about this?

I've lived in Asia for more than 22 years and have extensively traveled around the region, both for work and pleasure, from the Middle East and central Asia to Japan, and Australia, New Zealand, and every country in between. Asia is the perfect setting for a thriller, as a region that’s deeply rooted in traditions, but where modernity and growth are also breathless. There can be political instability at times, and even corruption, unsurpassed wealth and shocking poverty, bankers, and prostitutes. I worked for many years as an investment banker and my experiences inspired me to write my debut thriller, Hard Underwriting, in Hong Kong, and uncover the dark side of Asia’s financial capital.

This is one of the best books in Eisler’s John Rain series, featuring half-American, half-Japanese assassin and Vietnam veteran John Rain.

Eisler himself was a covert operative with the CIA’s Directorate of Operations, and his descriptions of fieldcraft, surveillance, torture, and killing techniques all ring so true, as does his extensive knowledge of modern Japan.

Tokyo is, of course, a fascinating playground for Rain’s adventures. Eisler’s books and unputdownable, and well worth discovering.

Book cover of Hungry Ghost

Jay Tinsiano Author Of False Flag

From my list on international thrillers to keep you turning pages.

Why am I passionate about this?

I’ve always been a big fan of thrillers, especially the ones where exotic locations offer a backdrop to the main story. I first picked up a pen and paper to start scribbling notes for my first novel while travelling in SE Asia. The sometimes eccentric characters I met, the heady, vibrant, and chaotic nature of budget travel, and some of the situations I found myself in all fueled my creativity. Somehow, I needed to get these experiences and thoughts down on paper. So, the elements of multiple international locations, exotic and not-so-glamorous, have inspired my writing over the last decade.

Jay Tinsiano Why Jay loves this book

This pulled me right into the world of British Hong Kong in the run-up to the Chinese handover in 1997. I listened to this one on audio with the flu, and it was a very welcome escape.

Multiple POVs and a great fleshing out of all the different characters make for a great, fast-paced read: A chilling ex-SAS Assassin, powerful Triads, Chinese assassins, and a hard-drinking Police Officer held back in his career. Some might say there’s too much going on, but I didn’t have a problem following the narrative. The setting of Hong Kong plays a crucial role, which HK expat Leather vividly describes with its bustling streets and seedy underworld, creating a sense of atmosphere that immersed me in the story.

I found it an intense and gripping novel that showcases Leather’s talent for crafting action-packed thrillers with layered characters. It’s a must-read for fans of crime fiction,…

Philippe Espinasse Why Philippe loves this book

This is the first book in Valerie Goldsilk’s extensive ‘Reliable man’ series about former Royal Hong Kong Police inspector-turned assassin Bill Jedburgh, who plies his trade across Asia – and beyond, and who is known to those who use his services only as (you would have guessed it), “the reliable man”.

This thriller is set in Pattaya, Thailand, and involves a high-octane chase between Jedburgh, triad devotees, and European mafiosos, amid the exotic scenery of Southeast Asia. Nothing is missing, including bar girls, massage parlours, and sophisticated shoot outs.

Goldsilk herself has lived in Hong Kong for more than 30 years and is married to a former Hong Kong policeman. The story feels authentic (if not politically correct!) and is well written, as are the other books in the series.

Highly recommended!

This is the latest book in Boczar’s Eric Ketch series, which follows the adventures of an American international man of mystery across Hong Kong, Macao, Thailand, Cambodia, Vietnam, and Burma, in the pursuit of rubies, exotic women, and ruthless assassins.

Boczar himself knows the region very well, having lived in Hong Kong for over three decades, and worked as a war correspondent, on the porous borders of the golden triangle and in Lebanon during the civil war.

The descriptions, whether of cities, weapons, smugglers, or guerilla fighters, all feel true, and Boczar knows only too well how to tell a convincing and edge-of-your-seat story that is difficult to put down.

Book cover of The Uncaged Sky

Ian Kemish Author Of The Consul

From my list on what courage really looks like.

Why am I passionate about this?

As a former Australian ambassador and crisis manager, I’ve worked at the coalface of international emergencies. The Consul draws on those experiences and on my deep respect for those who show extraordinary moral and emotional courage under pressure. I’ve known several of the authors on this list personally and followed their stories closely. These books, whether memoir or biography, all speak powerfully to the question of how individuals keep faith with themselves—and with others—in the hardest of circumstances.

Ian Kemish Why Ian loves this book

I came to know Kylie after her release, and I mention her case in my book. What she endured—over 800 days in Iran’s notorious Evin Prison—is almost unimaginable. But what shines through this account is her fierce inner life. Kylie writes with unflinching honesty about fear, betrayal, and resilience.

I admire the way she clung to her intellectual strength and personal integrity in the face of a brutal, dehumanising system. Her story is more than survival—it’s a fight to remain whole.

1 author picked The Uncaged Sky as one of their favorite books, and they share why you should read it.

What is this book about?

'The sky above our heads was uncaged and unlike us, free.'

The Uncaged Sky is Kylie Moore-Gilbert's remarkable story of courage and resilience, and a powerful meditation on hope, solidarity and what it means to be free.

On 12 September 2018 British-Australian academic Dr Kylie Moore-Gilbert was arrested at Tehran Airport by Iran's feared Islamic Revolutionary Guards. Convicted of espionage in a shadowy trial presided over by Iran's most notorious judge, she was given a 10 year sentence and ultimately spent 804 days incarcerated in Tehran's Evin and Qarchak prisons.

Book cover of Then the Fish Swallowed Him

Virginia Reeves Author Of Work Like Any Other

From my list on imprisonment both literal and figurative.

Why am I passionate about this?

The idea for my first novel came from a 1946 study of Alabama parolees, linking individual characteristics to the likelihood of recidivism. The outcomes were surprising in many instances: “promising factors” such as education, profession, and intelligence didn’t correlate with good behavior. This got me thinking about the lasting effects of imprisonment. Sentences don’t necessarily end when an inmate walks out the prison door. I see this again and again in the previously incarcerated students I teach at Helena College—they’ve been released from an institution, but mental and physical imprisonment lingers, and sometimes grows. The books on this list don’t shy away from that hard reality.

Virginia's book list on imprisonment both literal and figurative

Virginia Reeves Why Virginia loves this book

Set during the 2005 bus-driver strikes in Iran, this book explores imprisonment at nearly every level—from the confinement of a totalitarian regime to the physical and psychological torture of a political prisoner, to the locked doors of one’s own mind, to the escape sought (and sometimes found) in heroine. What sticks with me most, however, is the interior exploration of the main character, Yunus, and the way seemingly small decisions lead to enormous consequences. 

By Amir Ahmadi Arian ,

Why should I read it?

1 author picked Then the Fish Swallowed Him as one of their favorite books, and they share why you should read it.

What is this book about?

An critically-acclaimed Iranian author makes his American literary debut with this powerful and harrowing psychological portrait of modern Iran-an unprecedented and urgent work of fiction with echoes of The Stranger, 1984, and The Orphan Master's Son-that exposes the oppressive and corrosive power of the state to bend individual lives.

Yunus Turabi, a bus driver in Tehran, leads an unremarkable life. A solitary man since the unexpected deaths of his father and mother years ago, he is decidedly apolitical-even during the driver's strike and its bloody end. But everyone has their breaking point, and Yunus has reached his.

Book cover of The Handler

James E. Mack Author Of Asset Seven

From my list on spy reads by real life spies.

Why am I passionate about this?

I spent over two decades on the front lines of counterterrorism and counterinsurgency, working for many organisations and agencies around the globe. Having survived shootings, bombings, double agents, and kidnap attempts, I now prefer to write about such things rather than experience them! I grew up reading spy thrillers from the likes of Gerald Seymour and Frederick Forsyth and retain a passion for the genre. And there’s nothing better than reading a new novel, getting lost in the plot, and appreciating the realism or authenticity the author brings to the story. I hope you enjoy the books I’ve recommended that were written by real-life spies.

James E. Mack Why James loves this book

Another experienced intelligence officer, M.P. Woodward has created a terrific cast of characters for his series that begins with The Handler.

Once again, there’s a healthy dose of authenticity drawn from Woodward’s background that helps drive the plot forward.

A CIA operative, Meredith Morris-Dale, is assigned to extract an Iranian nuclear scientist with vital intelligence. The scientist, however, will only agree to the extraction if Meredith's ex-husband and former disgraced CIA paramilitary, John, carries out the operation.

Throw in internal CIA politics, Russian and Iranian spies, and the strained relationship of the divorced couple now working together and you have a terrific plot that races along.

A disgraced former CIA operative must go back in the field with only his ex-wife as his handler in this electrifying thriller from a former intelligence officer.

Book cover of Persepolis: The History and Legacy of the Ancient Persian Empire's Capital City

Michael Buckley Author Of Shangri-La: A Travel Guide to the Himalayan Dream

From my list on the best places you have never been to.

Why am I passionate about this?

I have a life-long interest in the intersection of the real and the mythical when it comes to travel and adventuring in foreign lands. This has driven my own exploration of many parts of Asia and the Himalayan regions. One tiny nugget of information can take you on a wild journey that leads to great discoveries. Curiously, we keep losing precious knowledge through war and neglect—and then re-discover it. The finest example of lost and found cultural facets has to be hieroglyphics. The meaning of the writing was lost for over a thousand years until the discovery of the Rosetta Stone in 1799, which enabled us to decipher Egyptian temple art again. So hieroglyphics entered the realm of the mythical and then returned to reality once decoded.

Michael Buckley Why Michael loves this book

The city of Alexandria was founded by Alexander the Great, or at least named in his honour. And Alexander the Great is responsible for wiping out other fabled cities. Most notably, the ancient Persian city of Persepolis, located in modern-day Iran. Finally, a place you can actually visit! But the massive palace lies in ruins, nowhere near its original splendour with all the statuary and furnishings, and the pomp and majesty of Persia’s kings and courtiers—at the time when Persia was a global superpower.

Around 2,000 years ago, Alexander the Great’s troops looted Persepolis and burned it to the ground. And there it lay in the sand, forgotten, until the site was revived in the 1930s and somewhat restored. The site lies in southwest Iran and was inscribed to the World Heritage List in 1979. Given that travel to Iran today is fraught with obstacles, this book about Persepolis could…

Danny Ramadan Author Of Crooked Teeth: A Queer Syrian Refugee Memoir

From my list on memoirs written refugees and immigrants.

Why am I passionate about this?

I have gone through the refugee experience, and it has shaped me. I grew up queer in Syria, became a man in Egypt, a refugee in Lebanon, then an author in Canada. At the expense of romanticizing something so deeply painful, I do believe that the experience has made me a better man. It matured me, offered me a deep connection with others within my community, and built an unmatched appreciation of my culture of home back in Syria and my culture of diaspora here in Canada. As a fiction writer, I am obsessed with writing queer stories about immigration.

I only knew of this book because my British publisher introduced me to it. For that, I’m truly thankful. The book feels honest and unflinching and makes for a great read for both myself as an immigrant as well as for those navigating a world where immigration is a constant daily reality.

I read it over a weekend in 2020 and have read it once more in 2022. I had to return to it, especially when I was faced with microaggressions or felt unheard in my new home in Canada.

What is it like to be a refugee? It is a question many of us do not give much thought, and yet there are more than 25 million refugees in the world.

All this while bearing the burden of gratitude in your host nation: the expectation that you should be forever thankful for the space you have been allowed.

Lois Pryce Why Lois loves this book

British-Iranian journalist, Ramita Navai shines a spotlight on 21st century Tehran that we rarely see in the mainstream press, delving into the city’s youth culture, illicit entertainment, and seedy underbelly of drugs and despair. City of Lies exposes the reality of how young, modern Iranians really live - constantly evading the authorities to seek out the pleasures they are denied under the regime.

What is this book about?

Absorbing and unforgettable, City of Lies travels up and down Vali Asr Street in today's Tehran, where the most ordinary Iranians are forced to live extraordinary lives. Ramita Navai paints an intimate portrait of the city's recesses where intrigues abound. Survival depends on an intricate network of falsehoods, and the difference between modesty and profanity, loyalty and betrayal, honor and disgrace is often no more than the believability of a lie.
