Luke’s doing his best to blend in to the background of high school, to ignore the haunting dreams spawned by his father’s Book of Eight, and to enjoy the one good thing to come from the whole mess: his girlfriend, Elza. And then it all begins again. Ash, a strange new girl with stark white hair, requests his help—and his Book of Eight—to save her twin sister, who was attacked by a demon. Ash knows a lot more about necromancy than Luke and seems to know what she’s doing, but can she be trusted?

Now that last year’s nightmare is in the past, Luke and Elza have started college, and Luke’s mum has moved on, too, with a new boyfriend named Darren. Life is returning to something like normal — until Luke and Elza spend New Year’s Eve at Darren’s cottage and find themselves transported to the forest near Dunbarrow with no knowledge of how they got there. Gray fog is spreading through town, the sky is awash with green light, and something is clearly very wrong: a great spirit from Deadside, known as the Barrenwhite Tree, has broken open the gateway between the living and spirit worlds, leaving Dunbarrow to be taken over by the world of the dead. Together with Luke’s old friends from school, who seem oddly unaffected by the plague of insanity unleashed on the town, Luke and Elza need to find a way to close the gateway while they still can. Not only that, but the devilish Mr. Berkley is abroad in Dunbarrow with an agenda of his own — and he hasn’t forgotten Luke’s debt to him. less
