In this magical companion to the National Book Award nominee A Tangle of Knots, it's summertime and everyone is heading off to camp. For Talented kids, the place to be is Camp Atropos, where they can sing songs by the campfire, practice for the Talent show, and take some nice long dips in the lake. But what the kids don't know is that they've been gathered for a reason--one that the camp's director wants to keep hidden at all costs.
