Ever since the brutal murder of his parents at the hands of a cult, Bellaydin Ap'Lydin has spent his entire life as the only human in a land of elves. Here, he and his half-sister Polnygar are barely tolerated, especially by the arrogant Spellweaver Lord Ivellios with his dreams of a purified elven kingdom. But after Polnygar stows away on a visiting envoy's ship, and Bellaydin is accused of murder, their whole world changes. Far from home and each other, they form new alliances and face challenges of their own. Assassins and cultists trail the siblings' every step in the name of their ancestor, General Lydin, and a lost artefact, the Tears of the Divine. As friends and family suffer death and misfortune, and the shadowy Horned God manipulates events from afar, the siblings are drawn into the prophecy of the Heir of Lydin. But is Bellaydin or Polnygar the Heir? Or is that a secret they should leave buried?
