What Readers & Critics Are Saying


In Coulson's thriller, a disgraced British soldier joins a secret organization of assassins. … A detail-rich adventure with a nuanced hero and plenty of explosions along the way.
Kirkus Reviews
A gripping crime thriller following an assassin longing for home and love. … Evokes the style of Frederick Forsyth and Robert Ludlum, delivering a tale of intrigue, danger, and the search for love and belonging. The story is slow-paced in the early pages, but picks up pace as it unfolds and maintains the momentum.

The Chrysalis Option brings a modern story and characters to a beloved genre. Whether Azunna was in a pub in the rainswept Brecon Beacons, or escaping from an enemy compound in Syria, the evocative descriptions made me feel like I was right there with her. It's been a while since a book has kept me up for just one more chapter before I turn off the light, but The Chrysalis Option kept me glued time and again.
Wing Commander James Brown, Royal Air Force
An excellent modern take on classic thrillers. Think Forsyth or Fleming for today. Kiana is a modern British spy with classic sensibilities fighting corruption and human trafficking. Written by an author who knows something about the subject and places he writes about, Chrysalis Option grabbed me early.

It is said you should write what you know, and if his characters and settings contain a kind of gritty realism that grabs you it's because Coulson served in Nigeria — and that shows. Anyone who has time in Nigeria will instantly recognize these locations and has known the people who have inspired his characters.

Such a fun read! British spy novel with female lead.

As a serving member of the RAF, I don't have much patience for thrillers that trade realism for Hollywood tropes. Eric Coulson's The Chrysalis Option is a rare exception that actually gets the grit and the tradecraft right. From the jump, Coulson nails the high-stakes atmosphere. Following Kiana Azunna's journey from the gruelling standards of the Royal Marines into the shadows of the Intelligence Service felt authentic. You can tell Coulson has immersed himself in the culture; his background as a Foreign Service Officer shines through in the tactical nuances and the way he handles the geopolitical friction between London and Nigeria. What struck me most was the pacing. It captures that military "hurry up and wait" followed by absolute chaos perfectly. Kiana isn't some invincible superhero; she's a professional dealing with a tragic past and an impossible mission. It's a sophisticated, high-octane read that stands tall alongside the greats like Forsyth or Ludlum. Five stars — I couldn't put it down.
