This summer at the cabin on Three Bird Lake, there will be no rowdy cousins tormenting Adam. No Uncle John or Aunt Jean. No Dad to fight with Mom. Just Mom, Grandma, and Adam. And Alice, the girl next door - who looks like the aloof, popular girls back home but is frank, funny, eager for adventure, and, most surprising of all, seems to want to be friends. When Adam's grandma starts to leave strange notes about hidden treasure and long-ago love, Alice is the one person who can help Adam solve the mysteries of Three Bird Lake.
