At first this seems like a teenaged first-love story, but it's so much more. Cadence at 15 falls in love with her aunt's boyfriend's kid (I think that's who Gat is); he's like part of the family but not really accepted by her grandfather, the wealthy successful patriarch who has high expectations for his grandchildren (and Gat is not the right pedigree). Nevertheless, Cadence loves him along with her cousins, whom she sees every summer at the family's residence on Martha's vineyard. But then Cadence finds she is recovering from a trauma; she can't remember what happened; the doctors want her remember in her own time. What I liked about this is that the traumatic event wasn't just accidental. Decide for yourself whose fault it was; everyone was desperate in a way. Teens will love this, as Lockhart throws in some fairy-tale analogies and switches up the format now and then to reflect Cadences state of confusion and sadness.
