Frantic by Katherine Howell
Couldn't put it down.
This book sets a cracking pace from start to finish and was full of authentic details. The kidnapping of baby Lachlan sets a series of seemingly unrelated events in motion.
The parents, Sophie and Chris, both blame themselves for different reasons and are prepared to give their own lives to save their baby. But it seems that everyone is lying about something and as the body count escalates, I wasn't having any more luck unravelling the mystery than the police.
