Rules for vanishing

"Once a year, a road appears in the forest. And at the end of it, the ghost of Lucy Gallows beckons. Lucy's game isn't for the faint of heart. If you win, you escape with your life. But if you lose . . . Sara's sister disappeared one year ago--and only Sara knows where she is. Becca went to find the ghost of Lucy Gallows and is trapped on the road that leads to her. In the sleepy town of Briar Glen, Lucy's road is nothing more than local lore. But Sara knows it's real, and she's going to find it. When Sara and her skeptical friends meet in the forest to search for Becca, the mysterious road unfurls before them. All they have to do is walk down it. But the path to Lucy is not of this world, and it has its own rules"--Provided by publisher.
