Arthur Parnassus lives a good life built on the ashes of a bad one.

He’s the headmaster of a strange orphanage on a distant and peculiar island, and he hopes to soon be the adoptive father to the six dangerous and magical children who live there.

Arthur works hard and loves with his whole heart so none of the children ever feel the neglect and pain that he once felt as an orphan on that very same island so long ago. He is not alone: joining him is the love of his life, Linus Baker, a former caseworker in the Department In Charge of Magical Youth. And there's the island's sprite, Zoe Chapelwhite, and her girlfriend, Mayor Helen Webb. Together, they will do anything to protect the children.

But when Arthur is summoned to make a public statement about his dark past, he finds himself at the helm of a fight for the future that his family, and all magical people, deserve.

And when a new magical child hopes to join them on their island home—one who finds power in calling himself monster, a name that Arthur worked so hard to protect his children from—Arthur knows they’re at a breaking point: their family will either grow stronger than ever or fall apart.
