They are connected in their dreams. Fifteen-year-old Gaby believes her soul leaves her body when she is asleep. She has vivid, three-dimensional, mega screen dreams, but they seem too real to just be normal dreams. After a car accident, Barclay is in a coma and every night he meets Gaby in her dreams under the lemon tree. When her gran gets ill, Gaby does not recognise the comatose boy in the bed next to her gran, but when she does, her dreams turn sinister and she realises she needs to save him and convince him to find his way back home.
