Cathrall’s debut caught me up on a wave of whimsy and swept me away with its charm.

I loved it. – Louisa Morgan, author of A SECRET HISTORY OF WITCHESA Letter to the Luminous Deep is like nothing I’ve read before. The heartfelt intimacy of the epistolary narrative, juxtaposed with the magnificent oceanic world-building, results in a novel that is at once deeply human and mind-bogglingly imaginative. Both the setting and the story are exquisite, but it was the lovingly crafted voices of the characters that kept me hooked from beginning to end – Megan Bannen, author of The Undertaking of Hart and MercyAn underwater treasure-chest to be slowly unpacked, full of things I adore: nosy and loving families, epistolary romance, gorgeous worldbuilding, and anxious scholars doing their best to meet the world with kindness and curiosity – Freya Marske, author of A MARVELLOUS LIGHTA shimmering, delicately crafted delight… Readers looking for heart warming romance and scholarly mystery against the backdrop of a wildly imaginative world will be charmed – H.G.
