In Falken, the sixth instalment of the Fernsby’s War series, J.C. Jarvis delivers a gripping, emotionally charged World War II thriller filled with espionage, betrayal, and relentless tension. Set during the London Blitz, British agent Michael Fernsby faces his most personal and perilous mission yet hunting a ruthless German operative who has infiltrated Britain’s intelligence network.
Jarvis masterfully captures the claustrophobic fear of wartime London and the psychological strain of divided loyalties. Each twist deepens the suspense, while the human cost of deception gives the story its emotional weight.
A taut, impeccably researched thriller, Falken is a powerful exploration of courage and conscience in the face of betrayal.

The sixth book in this terrific Fernsby’s War Series took a different turn than the previous books, as Michael Fernsby and Unit 317 are tasked with finding a traitor in their midst. As various members of their unit are killed/assassinated in England by a highly trained team from Nazi Germany, the storyline was filled with nonstop mystery, suspense, and action. I am already looking forward to the seventh book of the series; and, then, will take a hiatus from Fernsby’s War until the eighth book is published in 2026.

Book 6 - The Abwehr Spy Gladius within British Intelligence
This may be the best installment so far in this series, and I’ve given each of the prior ones five stars each! Senta, Mina and Fernsby are all here, with most of the story set in Britain this time during the Luftwaffe bombings of the latter half of 1940. Sleeper cells, Nazi commandos on English soil, and a deep mole within British intelligence. Hope you enjoy it as much as I did!

The Hunt Continues
Fernsby's hunt for for Nazi terrorists continues. But this time the hunt is at home in England. Fallen is full of suspense. I was unable to put this book until it's conclusion. A really good read. Highly recommend this series, especially if you like WW2 espionage.

wonderful
The books get better and better. My only regret is the next one is my last. The first two books great but they ended the same. After that the books were great. They extended into the next. Left a cliffhanger. Highly recommend. No I don’t give a review telling you the book, why read it? These are great, bad Nazi all the way through. Highly recommend.

Great book/series
It seems like this series improves with every book. It is evident that so much research has gone into these books. The characters are wonderful. The plot is very moving. Can't wait for the next book in series.

Delightful and intense reading
I’ve read each of Jarvis’ books. I’ve loved them all. Jarvis is a gifted writer who uses words and intrigue to engage the reader. I can hardly wait for the next volume to come out.

Fernsby’s War book 6
Excellent, edge of the seat stuff. The whole book range has been exciting, very well written and a reminder of the horrors committed by our former enemy’s (now friends) just 80 years ago.

Best so far
This was much more interesting than the previous books. They were much more predictable and if I’m honest we’re becoming boring. Hopefully the following books will be in the same vein

Breathtakingly good
The storyline was brilliant and grew slowly unravelling the dangers and the treachery. You felt David you were there amidst the action. Great descriptions at all times.

Action and intrigue
Taking place on British soil this book gives the reader an uncomfortable feeling as members of unit 317 are in mortal danger. A real nai biter.
