The disappearance of Winter's daughter

The Disappearance of Winter's Daughter is the fourth installment of Michael J. Sullivan's Riyria Chronicles, the prequel arc to his beloved Riyria Revelations. It once again pairs the cynical former assassin Royce Melborn with the honorable swordsman Hadrian Blackwater, the mismatched duo whose partnership anchors the entire Riyria saga. Hired to investigate a nobleman's missing daughter, the pair travel to the crumbling old-world city of Rochelle, where imperial pretenders, hidden magic, and buried history collide.

Widely regarded as one of the most action-packed and atmospheric entries in the Riyria books, the novel blends a self-contained detective mystery with the character-driven banter and moral complexity fans expect. Newcomers can read it as a standalone caper, while longtime readers will find threads that enrich the wider world of Elan.

Sullivan's clean, propulsive prose and tightly plotted intrigue make this a strong entry point into secondary-world fantasy that prizes friendship, wit, and hard choices.
