The BFG
by Roald Dahl (Puffin)

Sophie is unable to sleep one night when she sees an incredibly tall man with huge ears standing outside her window. This terrifying giant slips his arm through her window and into her room to take hold of her and bring her to his home. At first worried for her life, Sophie discovers him to be a kind giant, one who spends his nights walking about the streets to catch children's nightmares and replace them with dreams.
