Told in third person, the protagonist, Kip, is on an airplaine, headed to an island where his grandmother lives. At the island will be his five girl cousins. The house on the island has been sold and will be torn down - their last trip to this place. Grandmother allows writing on walls and demolition, as long as it doesn't compromise the basic structure and bring the roof down on their heads. Kip chooses to stay in the attic where he finds something that belonged to his father, now deceased, and it sends his imagination on a journey. I loved the five girl characters and the no-rules grandmother - well, no rules accept that she only cooks once a day and you don't want to know what happens if you leave dirty dishes in the sink. Nice imaginative, specific details and characterization.
