Selkie Stewart has grown up with strange rules: never speak of your birthday, never tell anyone your birth date, never ask about your mother. On her seventeenth birthday, the rules break — and so does everything else. Selkie discovers that her father is a faerie lord, her mother is the Seelie Queen who wants her dead, and the faerie court believes she is a child of prophecy destined to destroy their grip on the supernatural world. With Ben, her secret crush and unlikely ally, she must navigate the Otherworld to survive.

Selkie Stewart is funny, self-aware, and refreshingly non-annoying for a teenage protagonist — her narrative voice is one of the series'' greatest pleasures. She approaches an impossible situation with pragmatic humor rather than melodrama, and her genuine love for Ben feels earned rather than inevitable. Readers describe her as one of the most likeable YA heroines they''ve encountered.

Across two books, Selkie and Ben move from confused, newly revealed half-faerie to the two most wanted individuals in the Otherworld, fated to bring down the Seelie Court. The duology balances a light, witty tone with genuine stakes and a romance that is sweet without being saccharine. Skylar Dorset''s love for Boston gives the real-world sections a grounded warmth that makes the faerie incursions feel wonderfully disruptive.
