Matt Killeen was born in Birmingham, in the UK, back when trousers were wide and everything was brown. Early instruction in his craft included being told that a drawing of a Cylon exploding isn't writing and copying-out your mother's payslip isn't an essay "about my family." Several alternative careers beckoned, some involving laser guns and guitars, before he finally returned to words and attempted to make a living as an advertising copywriter and largely ignored music and sports journalist. He now writes for the world's best loved toy company, as it wasn't possible to be an X-wing pilot. Married to his Nuyorican soul mate, he is parent to both an unfeasibly clever teenager and a toddler who is challenging his father's anti-establishment credentials by repeatedly writing on the walls. He accidently moved to the countryside in 2016. Follow him @by_Matt_Killeen.
"A stunning, smart, grounded tale of intrigue in Nazi Germany, so guilty and detailed it feels like true memory rather than fiction. Sarah is an angry, appealing, heart-wrenching hero, superhuman and achingly frail in equal measure. I wish I'd written this myself. Deeply disturbing and chillingly good."--Elizabeth Wein, New York Times bestselling author of Code Name Verity
"I found myself mesmerized by Sarah's journey into a world of human monsters. Orphan Monster Spy weaves one heroine's courage through a spectrum of darkness, and the effects resonate long after the final page." --Ryan Graudin, award-winning author of the Wolf By Wolf duology
"Killeen expertly conjures the day-to-day evil of Nazi Germany in this terrific page turner."--Paul Dowswell, award-winning author of The Auslander
"A powerful, bleak, and penetrating portrait of an isolated young woman excelling in unimaginable danger."--Kirkus Reviews
