Twelve-year-old Shayne has always spent summers on the Maine coast, visiting her grandmother Bea and playing with her BFF Poppy. Both Shayne and Bea are collectors of sorts: Shayne revels in golden memories of weaving friendship bracelets with Poppy, while Bea scours yard sales for trinkets to add to the growing pile in her house, jokingly named Junk Mountain.
But this summer everything has changed. Poppy would rather talk boys than bracelets, and Bea’s collecting mania has morphed into hoarding. Only Linc, the weird Civil War-obsessed kid next door, pays attention to Shayne. Turns out Linc has collected a secret of his own. What begins as the worst summer of Shayne’s life becomes the most meaningful, as she wages an all-out battle to save her friendship, rescue her grandmother, and protect the memories she loves the most.
