Witch Blood -- Red Thread — Michael Ryan

It's Kim Murayama's third year on the prohibited island in the far northern reaches of Lake Superior, his third year with the cloned witches of Isle Royale, and he's becoming increasingly like them. Is it from the blood transfusion he received from his lover, Mick the Witch? Or is the truth something more troubling? When Kim discovers the Doors to Yesterday in the dull twilight of Limbo, he has the opportunity to uncover a number of disturbing truths, including that of his own existence.More mysteries of Isle Royale lurk in shadows beyond firelight and the other side of dreams. The enigma of the witches – what they are and what Kim himself may be – waits down uncharted paths and in undiscovered secrets of the heart.
