What a stellar concept for a book! McGuire asks the question - what would it be like to be a child who journeys to another world then has to return and try to reintegrate into our society? When your entire worldview has changed, can you just go back to pretending it never happened?
The answer for Nancy and the other Wayward Children in her "boarding school" is a resounding no. They want nothing more than to return to the otherworlds they visited. The ones that accepted them as they truly were in their hearts. Others (think similar to Dorothy in the Wizard of Oz) are more than happy to forget and move on, but Nancy simply can't. She finds both comfort and friendship with the only people who can understand, even partially, what has happened to tear her life apart. Not going to a foreign world... but having to COME BACK.
This novel is short, but absolutely stellar. Dark, mysterious, heart-wrenching, and lyrical. I cannot wait to delve back into this world with the next book in the series. Definitely a recommended read for fans of dark fantasies.
