«A'Choille Fhiadhach» by Kenny Lindsay

Ostracised at school because of her parents' eccentricity, Anna coped by inventing an imaginary friend called Pipkin, but when she started chatting to boys on the internet she soon forgot her childhood companion. Now a fuel crisis has thrown the island into chaos, leaving Anna without her social lifeline, and suddenly Pipkin is back, but this time he's real and more sinister than she ever dreamt he could be. With the villagers rioting and the neighbours threatening her family, Anna escapes to the forest, but can she escape from Pipkin?
