Praise for
Black as Diamond
"Black as Diamond is haunting and ethereal, balanced with the warmth of found family. This is a cast of characters you are bound to fall in love with as they fumble their way toward one another, seeking connection in a world that is falling apart.”—Andrea Stewart, Sunday Times bestselling author of The Bone Shard Daughter
“With vivid prose, bone-rattling action, and a queer romance as tender as it is thunderous, Black as Diamond is a dark fantasy gem from the glittering heart of the genre.”—Sophia Slade, author of Nightstrider
“This is the sort of fantasy I love. Layered, detailed world building, lush prose, lovable but flawed found family, and a central magical mystery tying it all together. Black as Diamond is a triumph!”—M. H. Ayinde, author of A Song of Legends Lost
“U. M. Agoawike combines truly epic world building and breathtaking action to create a wholly original, harrowing dark fantasy. Black as Diamond is a gut punch of a debut novel.”—Chelsea Abdullah, author of The Stardust Thief
“A wickedly original epic fantasy bound by the familiar threads of friendship, family, and fate. Agoawike's masterful worldbuilding is in rare balance with characters who shine bright within a world where nobody quite fits, and nothing is as it seems. Dark but boldly hopeful, Black as Diamond is fantasy at its most brilliant!”—Fiona Fenn, author of The Crack at the Heart of Everything
“Cast against a dark, lush world of intricate magic and dynamic characters, Black as Diamond is a fantasy of epic proportions.”—C. S. Pacat, author of Dark Rise, Captive Prince, and Fence

Novel
Black as Diamond (Bindery Books, March 2026)
Like the rest of the winged eresh keyel, warrior Asaru has spent his life fighting a long-dead enemy. When his brother’s squadron disappears from a border keep, Asaru travels into the human realm to investigate, only to become ensnared by a fatal—and unbreakable—curse that could wipe out his people. When he inadvertently commits a terrible crime, Asaru is thrown into the path of Wren, a former healer-in-training playing with dangerous magic. Bound to one another by a spell gone wrong, and on the run from freelance killers, they set out to find the Chronicler, who could bring them answers, redemption, and the cure to Asaru’s curse. But the secrets they uncover about the past have the power to break the world into pieces, ending human civilization and settling its remnants into something entirely new.
