The White Spire. Corrupted Coil, #5

With the Coil collapsing around their ears, Yann, Eliska, and Anríq must follow the last hopeless clues in a deadly race against time to find the Shards of Hotha before the Voyant Mendicat destroys the Coil and kills everyone in it. The Coil is already dangerous enough, but the worst lies ahead as the three friends' journey takes them into uncharted territories of nightmares, tempting fantasies designed to make them forget their quest, and ultimately, just might turn them into the very evil forces they've been working so hard to defeat.
When the war ends in one final epic battle, none of the friends may have the will or the power to save the Coil at all. They might just be the ones who cause its destruction along with everything they hold dear.
