Wilson, Nathan D

While his widowed mother continues to search for him, eleven-year-old Tom, presumed dead after drifting away down a river, finds himself trapped in a series of underground caves with another survivor and a dog, and pursued by murderous treasure-hunters.

As Henry York's time on his aunt and uncle's farm draws to a close, Henry makes a rash decision to step into one of the alternate universes hidden behind the cupboard doors and search for the truth about who his parents are and where he came from.

Twelve-year-old Henry York, finally reunited with his family, works with them and the Chestnut King, the long-deposed and mythic leader of the faeren people, to destroy Nimiane and her forces of evil.
