Percepliquis

The elves have crossed the Nidwalden River, and the empire's survival now depends on Novron's heir. Royce Melborn and Hadrian Blackwater, the two thieves who work as Riyria, sign on with a dangerous expedition heading for Percepliquis, the legendary buried city.

Beneath the ground, lost history and old horrors wait for the party. The descent is the heart of the book, and the partnership between the two thieves stays at its centre throughout.

Outside the expedition, the choices of Arista, Myron and the Empress Modina bear on how the war turns out. Their storylines run alongside the thieves' and are brought together here.

This is the sixth and final volume of the Riyria Revelations, first published in January 2012, and it closes the series' long-running plotlines.

It follows directly on from Wintertide and is best read after it. Both books are collected in the omnibus Heir of Novron. For readers who have followed the series from the start, the emotional weight of the finale falls on the bond between Royce and Hadrian.
