Charles Dickens is not feeling the Christmas spirit. His newest book is an utter flop, the critics have turned against him, relatives near and far hound him for money. While his wife plans a lavish holiday party for their ever-expanding family and circle of friends, Dickens has visions of the poor house. But when his publishers try to blackmail him into writing a Christmas book to save them all from financial ruin, he refuses. And a serious bout of writer’s block sets in.

Frazzled and filled with self-doubt, Dickens seeks solace in his great palace of thinking, the city of London itself. On one of his long night walks, in a once-beloved square, he meets the mysterious Eleanor Lovejoy, who might be just the muse he needs. As Dickens’ deadlines close in, Eleanor propels him on a Scrooge-like journey that tests everything he believes about generosity, friendship, ambition, and love. The story he writes will change Christmas forever.

Linus Baker leads a quiet, solitary life. At forty, he lives in a tiny house with a devious cat and his old records. As a Case Worker at the Department in Charge Of Magical Youth, he spends his days overseeing the well-being of children in government-sanctioned orphanages.

When Linus is unexpectedly summoned by Extremely Upper Management he’s given a curious and highly classified assignment: travel to Marsyas Island Orphanage, where six dangerous children reside: a gnome, a sprite, a wyvern, an unidentifiable green blob, a were-Pomeranian, and the Antichrist. Linus must set aside his fears and determine whether or not they’re likely to bring about the end of days.

But the children aren’t the only secret the island keeps. Their caretaker is the charming and enigmatic Arthur Parnassus, who will do anything to keep his wards safe. As Arthur and Linus grow closer, long-held secrets are exposed, and Linus must make a choice: destroy a home or watch the world burn.

An enchanting story, masterfully told, The House in the Cerulean Sea is about the profound experience of discovering an unlikely family in an unexpected place—and realizing that family is yours.
