Dive into the charming conclusion to the Sunken Archive duology, a heart-warming magical academia fantasy filled with underwater cities, romance of manners and found family, perfect for fans of Emily Wilde’s Encyclopaedia of Faeries.
 
Former correspondents E. and Henerey, accustomed to loving each other from afar, did not anticipate continuing their courtship in an enigmatic underwater city. When their journey through the Structure in E.’s garden strands them in a peculiar society preoccupied with the pleasures and perils of knowledge, E. and Henerey come to accept—and, more surprisingly still, embrace—the fact that they may never return home.

A year and a half later, Sophy and Vyerin finally discover one of the elusive Entries that will help them seek their siblings. As the group’s efforts bring them closer to E. and Henerey, an ancient, cosmic threat also draws near…

  • Praise for A Letter to the Luminous Deep:

    "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." B>Freya Marske

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

    "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. The lovingly crafted voices of the characters kept me hooked from beginning to end." B>Megan Bannen

    “A shimmering, delicately crafted delight of a book, steeped in love for the wonder of nature and the vagaries of archival research.” 
    H. G. Parry
