Kip is spending the summer with his grandmother and his five eccentric girl cousins, including Emily, who thinks she’s a dog. Gran’s house is about to be demolished, so anything goes, whether it’s drawing maps on the wall or sawing off the banister for a smoother ride. When Kip bashes through an old closet, he discovers the binder his late father kept as a teenager. He’s bewildered by what he finds: puzzling lists, hair samples, old newspaper clippings, and business cards — all accompanying a confidential report written by a mysterious young operative who is carrying out a secret plan to infect teenagers with a cell-altering virus. When the cousins tell Kip he needs to think up something to do for Talent Night, he panics — until he remembers the binder.
