For as long as he can remember, Adam and his parents have spent their summers at his grandmother’s rustic cabin on Three Bird Lake. This year, the lake will belong just to Adam…and, apparently, Alice, the girl next door. Alice seems to want Adam’s friendship, but she looks just like the aloof, popular girls back home - what could they possibly have in common?

When Adam’s grandma starts to leave strange notes in his room - notes that hint at a hidden treasure somewhere at the lake and a love from long ago - Alice is the one person he can rely on to help solve the mysteries of Three Bird Lake.
