After being shot in the back and dying - again - Harper's recovery has been hard. She's lost many of the powers she'd acquired since first becoming a Greywalker and knows that if she dies one more time, she won't be coming back. Her only respite from the chaos is her work ...until she sees a ghostly car accident for which there are no records. Worse still, the victim of the fatal wreck insists he was murdered, and that the nearby community of Sunset Lakes - called 'Blood Lake' by locals - is to blame. The picturesque area is an unlikely a haven for conspiracy but Harper soon learns that the icy waters of the lake hide a terrible power and a host of hellish beings. And both are held under the thrall of a sinister cabal that will use the darkest of arts to achieve their fiendish ends ...
