All is not well in Glassholm. Life under the moon has always been so predictable: day follows night, wax phases to wane and, after the despair of every Darkday, a person’s mood soars to euphoria at Full. So it has been for five hundred years, ever since the Lunane captured the moon and tethered it to the city.

Now, all that has changed. Amidst rumours of unsettling dreams and strange whispering children, society is disintegrating into unrest and violence. The very sea has turned against Glassholm and the island’s luck monkeys have gone wild, distributing new fates to all and sundry. Turmoil is coming.

Three people find themselves at the eye of the storm: a former policeman investigating a series of macabre murders, an outsider artist embroiled in the murky intrigues of revolution, and a renegade engineer tasked with fixing the ancient machine at the city’s heart. Each must fulfil their role or see Glassholm shaken apart, while all are subject to the machinations of their inscrutable and eternal monarch, The Moon King.


“A truly unique fantasy, The Moon King is a mysterious, luminous read, full of intriguing characters and featuring a twisty, page-turning plot. Beautifully written and thoughtful. Sure to be one of the best debuts of this or any other year.” – Jeff VanderMeer

“A vivid evocation of a strange moon-ridden bipolar world that swings each month from delirium to despair, and the sort of book that creeps into your dreams.” – Chris Beckett, Arthur C. Clarke Award-winning author of Dark Eden.

"Williamson has woven a story that teems with ideas and imaginative power. There is beauty in it, and strangeness, and page-turning adventure. The marvellous conceit at The Moon King’s core also conveys a powerful message about man’s relationship with nature and with his environment. The commitment shown to the characters by their creator is intense, and palpable. An intricately constructed, heartfelt novel that does its author proud.” Nina Allan, author of The Silver Wind
