Toronto is a werewolf, with no childhood that he can remember. He has attached himself to Rafe's group but tends to be unreliable, lost. Long white blonde hair, a confrontational attitude, and a Master unaware of all of his powers makes Toronto someone to notice.
Sylvia is a vampire, with a childhood that haunts her dreams at night. She is a killer for hire, but will do some jobs free if the cause is right. This current job has the right cause.
Early on in the story, Toronto and Sylvia decide to join forces because they are both hunting the same person.
Witches and psychics take an important secondary role in the story. These two realize half way through the book that things are much bigger than they seemed at first. Problems multipy quickly but Toronto and Sylvia need each other to do the job. Passion is hot, the road to love is very twisted and bumpy, and important personal observations by both the heroine and the hero is addictive.
