This haunting young-adult novel weaves together two mysteries: an engrossing whodunnit and also the enigma posed by the young woman who could play a role in solving it: Maggie Warshauer, a budding scientist and keen observer of the natural world.
Maggie lives on a cramped and run-down houseboat with her father, Drew, who manages the marina where the boat is docked. Although Drew clearly loves Maggie, his struggles with alcoholism leave him unable to be fully present for her. So does his inability to let go of his relationship with his ex-wife (“my so-called mother,” in Maggie’s words). He writes to her regularly, begging her to come back to him and Maggie. But without fail, the ex returns the letters to him, apparently unread. Drew’s limitations as a parent push Maggie into the role of caring for herself, and often, for him as well.
