The circle at the hollow tree - Billy Roberts

Born into a wealthy Cornish family, ten-year-old Simon Halifax is cruel to animals and has no regard whatsoever for anyone but himself. His abuse of nature and his privileged life eventually cause him to be enticed into a secret world, ruled by a sacred gnome-like race whose very existence depends on the balance and preservation of nature. Once there, Simon is forced to face the products of his own malevolence-Lithom's giants, and goblins whose sole intention is to enter the Jesnick Kingdom, and then gain access into Simon's world through the Circle At The Hollow Tree, the portal to the Jesnick Kingdom. On Simon's return to his world, he is left wondering-did it really happen to him, or was it all just a dream?
