Sylvie Cathrall’s debut fantasy, a series opener, offers an aquatic variation on dark academia, unfolding entirely through a series of letters and other documents. Set 1,000 years after a mysterious event called “the Dive” sent almost all of humankind underwater, A Letter to the Luminous Deep (12.5 hours) begins with reclusive E. Cidnosin writing to scholar Henerey Clel about her discovery of an unidentified “elongated fish.” Listeners soon discover, through letters between E.’s sister, Sophy, and Henerey’s brother, Vyerin, that E. and Henerey have disappeared under unexplained circumstances. Part mystery, part slowly building romance, Cathrall’s lyrical fantasy utilizes poignant details and quaint language to conjure an evocative underwater world. The use of different narrators for each letter writer—Claire Morgan, Kit Griffiths, Justin Avoth and Joshua Riley—is an effective way to differentiate the characters, and the novel’s unhurried pacing allows listeners to relish the art of letter writing.
