When Liam's sister dies, his world turns grey. He spends hours watching clouds crossing the wintry skies, hoping that Cassie is out there somewhere. On the night before Liam's birthday, Cassie sails the Sky Dreamer to their home and drops anchor in a ghost gum tree. She invites Liam to climb aboard, and together the children go sailing through the Milky Way. But there are lessons Liam must learn before the Sky Dreamer returns home. The Sky Dreamer is an achingly beautiful and ultimately comforting picture book about a young child learning to take control of his life after the death of a loved one.
