Peat is on the run — forced to flee for her life when she's blamed for bringing bad luck to her village. She heads for the endless marshes, where she's caught by an old healer-woman who makes Peat her apprentice and teaches her the skill of storytelling.

But a story can be a dangerous thing. It can take you out of one world and leave you stranded in another — and Peat finds herself trapped in an eerie place beyond the Silver River where time stands still. Her only friends are a 900-year-old boy and his ghost hound, plus a small and slippery sleek — a cunning creature that might sink his teeth into your leg one minute, and save your life the next.
