If you were drawn to Kaleb's cold, enigmatic nature and his willingness to walk the line between hero and villain in Heart of Obsidian, you'll be captivated by Dmitri in Archangel's Blade. Dmitri is a centuries-old vampire with a dark past and questionable ethics, whose loyalty and vengeance drive the story. The book delivers the same morally grey intensity and emotional depth between characters, making it a perfect next read.

Did you love the relentless drive and razor-sharp focus Kaleb showed in his mission to save Sahara? Gladiator offers a similarly pulse-pounding plot: Harper, a human abducted by aliens, must survive brutal gladiatorial battles and fight for freedom alongside the formidable gladiator Raiden. The story is propelled by urgent, clear objectives, and every moment is fueled by high stakes and determination.

If you appreciated Kaleb and Sahara's journey toward healing and trust, you'll be moved by the slow-burn transformation of Kiem and Jainan in Winter's Orbit. Both characters are thrust together in a political marriage and must confront trauma, secrets, and vulnerability. Their emotional growth and evolving relationship offer the same satisfying, heartfelt payoff.

If the rapid pacing and constant tension in Heart of Obsidian kept you turning the pages, you'll love Polaris Rising. Ada von Hasenberg is on the run from a powerful family, and her alliance with the dangerous fugitive Marcus Loch leads to explosive action, quick escapes, and sizzling chemistry. The story moves at breakneck speed, just like your favorite Psy-Changeling installment.

If you were fascinated by the intricately layered psychic abilities and societal structures of the Psy-Changeling world, Ninefox Gambit will blow you away. The novel introduces a complex universe where mathematics, calendrical heresies, and military factions shape reality itself. The richly detailed setting and unique systems will immerse you in a world as inventive as Singh's.
