Map of Flames (the Forgotten Five, Book 1)

"Fifteen years ago, eight supernatural criminals fled Estero City to make a new life in an isolated tropical hideout. Over time, seven of them disappeared without a trace, presumed captured or killed. And now, the remaining one has died. Left behind to fend for themselves are the criminals' five children--Birdie, Brix, Seven, Tenner, and Cabot--each with superpowers of their own. After her father's death, Birdie finds a map among his things that leads to a secret stash...and a note: 'Go to Estero, find your mother, and give her the map.' The five have lived their entire lives in isolation. What would it mean to follow the map to a strange world full of things they've only heard about, like cell phones, cars, and electricity? A world where, thanks to their parents, being supernatural is a crime?
