The missing family

Can David Raker solve a pair of impossible disappearances?

It's a warm, sunny day and the Fowler family are heading to the water. Sara and her daughter, Mable, stay on the shore while Marc, his son and his son's girlfriend set out on the lake. Sara closes her eyes for just a moment. She has no idea she's about to wake up to a nightmare. Her husband, son, and son's girlfriend have vanished without a trace. The boat is floating empty on the water.
The police are baffled, so David Raker, a specialist in finding missing people, takes on the case. But this time, he may have stumbled upon a mystery that even he can't solve. How could three people disappear from a boat in the middle of a lake in a single minute?
And how is all this connected to an escaped murderer who vanished from a locked holding cell in a London casino? Raker turns to his friend Colm Healy for help with the investigation. He has no idea that they are both hurtling towards a darkness from which there may be no return.
Some secrets are meant to be revealed, while others... should stay buried forever.
