He killed his daughter. Now he's taken his son.
Ingrid Skyberg joined the FBI to bring one man to justice: the man who abducted her best friend when she was fourteen. It's been eighteen years and she's never stopped looking for him . . . or for the friend who has never been seen since. Today's the day she's finally going to get some answers.
But before she gets the phone call she's always dreaded, Ingrid - the FBI's criminal investigator in London - receives orders from the Pentagon to track down a pilot who has gone AWOL from a US Air Force base in rural Suffolk. 
Accused of murdering his baby daughter, he's now abducted his eight-year-old son and gone on the run.
Ingrid must act fast to stop the pilot doing something no one will forgive him for, but a terrifying turn of events lands Ingrid in the greatest danger, just as haunting memories from the past threaten to engulf her.
