'Leo Lennox has an epic problem. It’s his thirteenth birthday and he has just grown a tail. If it’s not disastrous enough that the scaly growth has torn through the back of his pants in the school library, it turns out to be the first stage in the rapid and total implosion of his life.

'Now, as he discovers an unthinkable family secret, Leo must team up with his infuriating older sister to escape snake-skinned henchmen, ancient shape-shifters and a whispering villain determined to feed him to a pack of genetically engineered killer pigs. All while trying to get his secret crush to notice him.'
