Lies - Michael Grant

This is a blood-pumping, white-knuckle sci-fi thriller of epic proportions. It happens in one night: a girl who died now walks among the living, Zil and the Human Crew set fire to Perdido Beach, and amid the flames and smoke, Sam sees the figure of the boy he fears the most - Drake. But Sam and Caine defeated him along with the Darkness - or so they thought. As Perdido Beach burns, battles rage: Astrid against the Town Council; the Human Crew versus the mutants; and, Sam against Drake. And the prophetess Orsay and her companion, Nerezza, are preaching that death will set them all free. As life in the FAYZ becomes more desperate, no one knows who they can trust.
