Ryan Kaine is on the trail…

When a car crash kills a woman and leaves her husband in hospital, Ryan Kaine answers the call. One of The 83 is in trouble, and the police believe he’s to blame. But Kaine knows better.

As he digs deeper, Kaine uncovers a web of lies and intimidation that leads straight to a violent crime family who will do anything to bury the truth.

With a grieving man’s freedom at stake, two children in danger, and a killer determined to silence them all, Kaine must act fast before more lives are lost.

Trapped and outnumbered, he’ll have to fight harder than ever just to survive.

Alone and facing mounting odds, can Kaine prove a man’s innocence, make sure the real perpetrator faces justice, and protect a family from retribution?

With over half a million copies sold, the Ryan Kaine series has become a must-read for fans of Lee Child, Jack Lively, and Robert Ludlum.

Kerry J Donovan was born in Dublin. A citizen of the world, he now lives with his partner, Margaret, in Newark on Trent, Nottinghamshire. He has three children and four grandchildren. When he's not creating more mayhem for Ryan Kaine and DCI David Jones to clean up, he's riding the countryside on his motorbike, keeping fit by running and swimming, and doing little bits of DIY.
