Book cover of Spies Like Me

Robin King Author Of Remembrandt

From my list on spy books for Ally Carter fans.

Why am I passionate about this?

When I realized I didn’t have what it takes to join the CIA, I made it my life mission to find out everything it takes to be a spy—which, of course, made it necessary to watch every show and read every espionage story ever told. In the process, I discovered a passion for uncovering truth, as well as a love of writing. After writing three young adult spy novels, I feel like I’ve found the linguist, code breaker, and crime fighter in myself. My work for LitJoy Crate has given me the ability to know a good story when I read it, and then recommend that book to book lovers everywhere.

I’ve never wanted to be a spy so much until I read this book by Doug Solter. This fast-paced story made my heart beat fast because of the action and the romance! There were so many diverse characters, cool spy gadgets, and girl power. The drama of deep family secrets and a ruthless villain made me want to keep reading until I reached the final page.

There are lots of twists and turns that make you second-guess what you thought you knew. And the romance with a handsome and complex boy is one that pulled at my heartstrings and made me root for them so much. I loved this teenage version of Charlie's Angels, and I know fans of Ally Carter’s books will feel the same.

Robin King Why Robin loves this book

The action and adventure in this story were perfect for the thrill-seeker in me. I already knew that being an undercover agent as a teen would make for an interesting storyline, but then the author makes Christy join a group of adrenaline junkies, and the stakes keep getting higher, and the thrills keep getting scarier.

The thing that I loved most about this book was how each chapter end left me hanging and I had to keep reading to find out what happened next. I especially felt a kinship for Christy because, even though she is a teenager who is learning who she is, she is also a protector who has been enlisted by the FBI to save people. There is also a storyline of true love and friendship that grounded me and made me feel for the characters.

Robin's book list on spy books for Ally Carter fans

Robin King Why Robin loves this book

I fell in love with the main character, Loveday (no pun intended), in the first few pages. She’s strong and tough, like all spies should be, and sarcastic—which is so fun to read.

I love her motivation as a spy, but she does have one flaw: she's in love with another member of the team and has been keeping him off missions to keep him safe. This makes me like her even more because she wants to protect him. Overall, the action, explosions, love story between Loveday and Vale, and the spy world had me reading until the very end.

I can’t wait to jump into the next book in the series.

I was hooked the minute I started reading this cute spy thriller. The romance is sweet, and the suspense is cozy. I think because I’ve always been a fan of Ally Carter, this series was the perfect next book to read. After reading it, I now want to be part of the Banana Club and go on undercover missions.

I left like the book was a perfect blend of Charlie’s Angels meets Nancy Drew. I also enjoyed the fast-paced action and the out-of-this-world gadgets. I even found myself laughing out loud at some of the humor. I can’t wait to read more books about Mari, Hannah Anna, and the rest of the team!

Mark Simmons Author Of Room 39 & The Cornish Legacy

From my list on espionage that reach the core of the spies’ world.

Why am I passionate about this?

I have been passionate about the world of espionage ever since I saw James Bond for the first time on the silver screen. I read Ian Fleming’s books in those early Pan editions and entered the exotic world of devious enemies, exotic locations, fast cars, and women. After service in the Royal Marine Commandos, I began writing in 1984. To date, I have written sixteen books and over 200 articles. Eight of the books are espionage-themed. The rest are military history and historical novels. 

Mark's book list on espionage that reach the core of the spies’ world

Mark Simmons Why Mark loves this book

The first section of this book feels so accurate in its depiction of the Smersh (death to spies) training camp that I hardly missed 007 at all, who appears on page 95 in part two of the book. I first came across James Bond when my sister, who was three years my senior, got me to see the 1963 film. I was twelve at the time. I wonder what today’s politically correct regime would have to say about that? My sister was probably underage as well but looked older, so she passed muster.

This book is my favorite of Fleming’s Bond books. I have read it many times, yet when I pick it up to start again, there is that air of excitement; I can almost smell the exotic location of Istanbul, Bond being pitched against a dangerous adversary, and, to top it all, the remarkable character, Colonel Rosa Klebb,…

William Le Queux’s Duckworth Drew was a secret agent working for British embassies around Europe reporting to the Marquis of Macclesfield, the Secretary of State for Foreign Affairs. Like many such agents to follow, he worked in diplomatic and aristocratic circles with finesse and had considerable luck with the ladies.

In short stories like “The Secret of the Submarine,” Drew starred in adventures that were precursors to later yarns focused on new technology as when he encountered an "electronic eye," an Italian device that detonated mines. Such playfulness with then cutting-edge tech reflected the author’s interest in merging adventure with weaponized science.

Book cover of Spy/Counterspy: The Autobiography of Dusko Popov

Alan Cook Author Of East of the Wall

From my list on fiction and nonfiction about spies.

Why am I passionate about this?

I have always been intrigued by history, fictional and nonfictional. Unfortunately, warfare is a large part of history and spying is an important part of warfare, and is as old as warfare itself. If you want to win the war you need to know as much as possible about what your enemy is planning to do. I am also a puzzle solver, and making and breaking codes play a large part in spying. I have traveled widely and been to most of the places I write about. However, I am a pacifist at heart, and I keep looking for the key to world peace.

Dusko Popov may or may not have been a model for James Bond, but he did know Ian Fleming. He was also one of the most effective double agents in World War II. His greatest accomplishment was helping to fool the Germans about the location of the D-Day landing. Popov had conclusive evidence that the Japanese were going to attack Pearl Harbor months before it happened. He told FBI Director J. Edgar Hoover, because the US didn't have an effective spy system yet, but Hoover wasn’t interested. After the war ended, Popov searched for his best friend who had been captured by the Germans, with surprising results. Good for history junkies like me, it contains facts not present in other histories of the War.

Helen Fry Why Helen loves this book

The Secret Intelligence Service, SIS and also known now as MI6, is one of Britain’s most secret organisations, and as such has provoked intrigue, mystique, and fascination; all partly fuelled by Ian Fleming’s successful James Bond novels. But whilst there is some crossover at points with the fictional world, the official history makes it plain that much of its work was mundane. That does not lessen our interest in the organisation. This book provides the first authorised recognition that SIS existed, but also the first glimpse into its clandestine activities. Told chronologically rather than thematically, there is a sense of the developing history of the organisation, from the threats in 1909, through to the deceptions and counter-espionage ops of the First and Second World Wars to 1949 (the start of the early Cold War). The book is the first insight into some of the central characters – those who can…

From my list on women who rescue themselves.

Why am I passionate about this?

I love reading crime but oh, it does annoy me when an otherwise competent sensible female detective insists on going into the lonely house to tackle the murderer without backup, and needs to be rescued by her male sidekick. Cass is the cool-in-a-crisis heroine we’d all like to be. Like her, I’m a solo sailor (I’ve lent her my yacht for the series) and I’d love to say I’ve learned to be quick-thinking, self-reliant, and prudent—the sea doesn’t forgive stupidity. I also live in a village where everyone sees the lifeboat going out, and having to be rescued would be the ultimate embarrassment.

Leaving a trail of broken laws behind her, she gets herself illegally into France to join Bett, where her dreams start coming true: a sports car, a transmitter disguised as an earring, a casino, and a gun she now knows how to fire...  and it’s all narrated with Brookmyre’s trademark humour.

This is the latest in a series that is a clever parody of the James Bond series of books by Ian Fleming. 

Haris Orkin is an excellent writer who has built this series around his charming protagonist, James Flynn, who you cannot tell if he is crazy or has the deepest and most brilliant cover story imaginable – a patient in a psychiatric hospital.

While it is told with a tongue firmly planted in cheek, there is plenty of real action and adventure. It is a great escape from the mundane everyday life.
