Critics Review

Espionage, action, terrorism, cage fights, motorcycles, mystery and mayhem, C.J. Merritt delivers the goods and then some! Octagon bleeds authenticity from the first page to the last. Read it today! – JACK CARR, #1 New York Times bestselling author of Cry Havoc
An espionage novel that moves fast and hits hard. Stella and Tommy are wonderfully drawn protagonists, damaged but fiercely loyal to each other and to their country, and the plot is current and very scary. Highly recommended. – M.W. Craven
I hate this book, for keeping me up all night. Psychological insights, authentic tradecraft, sharply-drawn characters and a compelling plot grab the reader with a grip as tight as Tommy Kane’s. Well-observed prose engages them with all the charismatic poise of Stella McRae. Bourne meets Smiley, with exquisite balance. – Julian Fisher, author of Think Like a Spy
Octagon blends high-stakes, high-octane spy fiction with cryptic clue intrigue and a side order of globetrotting action adventure. A blistering thrill ride! – VASEEM KHAN, author of QUANTUM OF MENACE
A smart, slick, adrenaline-fuelled adventure for today’s fans of Ludlum and Fleming. – CHARLES CUMMING
A gritty, well-paced, page-turner. – The Critic
A classic ticking-clock thriller … fast-moving, full of surprises and very hard to put down. – James Wolff, author of Spies and Other Gods
A timely tale of the dangers of extremism lying just beneath the surface, of the dark web and cults of personality, Octagon will enthrall, grip, and spook you in equal measure. Will have you turning pages at breakneck speed. A top-shelf spy thriller from someone who knows his stuff. – I.S. Berry, author of The Peacock and the Sparrow
OCTAGON plunges the reader into a nightmarish nuclear conspiracy that spans the European continent, from the darkest woods of Scandinavia to the Adriatic coast. Short on options, time and resources, the protagonists of this breakneck espionage thriller untangle a web of threats, opportunities and uneasy alliances that left my head spinning. An authentic and compelling spy novel that hooked me from the opening scene. – DAVID GOODMAN
Here you have everything you look for in a spy thriller: action, suspense, drama, deft plotting and gritty realism. Buy now. – ALAN JUDD
