The story follows a boy named Christopher who stumbles upon a magical Archipelago. It is home to all manner of mythical creatures such as griffins, sphinxes, and centaurs. Alongside Mal, a girl with a flying coat and a baby griffin, Christopher embarks on a quest to save these magical creatures.

The book has been praised for its richly built world drawing comparisons to classics like His Dark Materials and The Chronicles of Narnia. The Guardian wrote, “Rundell's first foray into fantasy is both a deft, rich homage to the greats of children's literature and an absorbing, profoundly poignant quest story for those aged 9+ – quite possibly her best yet.”
