The Icarus Girl by Helen OyeyemiRead about the other entries on the list.
Eight year old Jessamy lives in London with her Nigerian mother and British father. On a visit to her mother’s family in Nigeria she meets her first real friend, a girl she calls TillyTilly. TillyTilly takes Jess to forbidden, impossible places and makes her see the things differently. Jess goes home to London: a little while later TillyTilly turns up saying she’s just moved in nearby. It takes Jess a while to realize that no one else can see her new friend, and she struggles to resist acting on TillyTilly’s more destructive ideas. Through her new friend Jess discovers a truth about herself that she had never consciously known before, but which, perhaps, has been at the root of her anxiety all along. Sinister and scary, this is a gripping read all the more impressive because of the fact that it was written while the author was still at school.
