Icarus Girl, The (2005)

Eight-year-old Jessamy meets TillyTilly during a visit to her mother's family in Nigeria, and the strange friendship follows her back to England. Oyeyemi turns the difficulty of belonging in two places into an increasingly frightening uncertainty about another child's presence. Choose it for a close, uneasy voice and a movement between domestic life and the uncanny. This is an adult literary novel with a young protagonist, not a reassuring adventure about an imaginary friend.
