Phoebe Stone, author of the sleeper hit Deep Down Popular, is back with a middle-grade code-breaking mystery full of romance and excitement. Think Chasing Vermeer meets The Secret Garden! Felicity's glamorous parents have a secret. When they leave her with distant relatives in Maine, far away from the battles of WWII, Felicity hopes they won't be gone for long. Her new Uncle Gideon hides things. Her Aunt Miami is star-crossed. And Derek, a kid her age, refuses to leave his room. But Felicity needs Derek's help. Gideon is getting coded letters from Felicity's parents, and she's sure they're in trouble. Can Felicity crack the code, heal the family and save her parents, all while surviving her first crush? It's a tall order, but — like The Secret Garden's Mary Lennox before her — Felicity's up for the challenge.
