Sixteen year old Felicity Carter has saved the life of an injured Scav, and now they're both in mortal danger. It's not just the repressive Kingsmen with their powers of instant execution, who want to get their hands on the boy and his secrets; there are forces far more dangerous who will stop at nothing, not even murder. For Flick, her small Oxfordshire town is no longer safe. Wanted for murder and with no one left she can trust, she must run. Or die.
