When his uncle's life is threatened by a vengeful ghost, Toby is sent to Tintagel, Cornwall; a mysterious village with obvious King Arthur connections. Once there, he discovers that his uncle is bound by many things magical, least of all a dangerously personal connection with the ghost. During Toby's desperate investigations and with the help of Arty, a half-elven, rambunctious young man, they discover that beneath modern day London are tunnels full of hags, sirens, trolls and other magical creatures with plans that could destroy the known world. But Toby's careless determination to protect his uncle leaves him in a deadly realm beyond the help of humans and surface dwellers. He has a simple choice: fight or die. This modern day fantasy novel is the first in the exciting new Toby Fisher series by Ian McFarlane... a celebration of all things magical, Merlin, and King Arthur.
