Sorrows. The Worldwalkers Universe, #1

Wrenched from his ordinary life by a violent madman and turned into a vampire against his will, Jayson Wallace must learn to adapt to a world he never knew existed; a world full of magic and wonder, where vampires, donors, and shapeshifting rael-shaa travel between quantum realities. It's a dream come true... but not his dream. His sleep is haunted by blood and fear, and a terrifying voice that he cannot shake from his memory.
The Circle who rescued him do their best to help, but a terrible betrayal sets off a cascade of events that give them problems of their own to deal with. Despite a growing relationship with a beautiful young donor, and a strong friendship with a lupine shapeshifter, Jay finds it difficult to accept the contrast between the idyllic reality before him, and the brutal torture he endured. To make matters worse, somewhere, out there, the monster who changed him still runs free...
