Successful graphic novelist Willow Tate is a Visualizer, able to draw beings from the Otherworld-home to trolls and elves, night mares and bird fish, and many other fantastical beings-and "draw" them into our world. Somehow they all seem to end up in the weird little town of Paumanok Harbor, nestled in the popular Hamptons region of Long I sland. As if Willow didn't have enough problems coping with all these Otherworld visitors, now she has a stalker, her doom-seer father has a secret, and Paumanok Harbor has Otherworld sand-stealers. Willow has bodyguards but absolutely no idea how to solve any of these problems in time for Halloween, when the local witches hold their annual gathering on the beach-if any beach is left by then. Good thing she has the handsome, loving, local vet Matt to come to her assistance.
