A Letter to the Luminous Deep

"This book is not shaped like a book, and I mean that as a compliment. It is instead an 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. Take a deep breath and dive in."

"Cathrall's debut caught me up on a wave of whimsy and swept me away with its charm. A story to be cherished."

"A fascinating and charming story told in a uniquely elegant voice. A watery wonder of a novel! I loved it." 

"A 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."

“A shimmering, delicately crafted delight of a book, steeped in love for the wonder of nature and the vagaries of archival research. Readers looking for heartwarming romance and scholarly mystery against the backdrop of a wildly imaginative world will be charmed.”

"With its gorgeous underwater setting and whimsical academic sensibility, A Letter to the Luminous Deep is a strange, epistolary wonder."
