Book excerpt: It’s Rachel Morgan’s ultimate adventure . . . and anything can happen in this final book in the New York Times bestselling Hollows series. Rachel Morgan has come a long way from her early days as an inexperienced bounty hunter. She’s faced vampires and werewolves, banshees, witches, and soul-eating demons. She’s crossed worlds, channeled gods, and accepted her place as a day-walking demon. She’s lost friends and lovers and family, and an old enemy has unexpectedly become something much more. But power demands responsibility, and world-changers must always pay a price. Rachel has known that this day would come—and now it is here. To save Ivy’s soul and the rest of the living vampires, to keep the demonic ever after and our own world from destruction, Rachel Morgan will risk everything. . . .
