2018’s The Ninth Rain is the first volume in Jen Williams’ Winnowing Flame trilogy.
Once the Eborans were rulers and guardians of their world; they were sustained and armed by their tree-god Ygseril. Eight times they fought the Jure’lia, invading horrors from beyond the sky. Eight times they won. In the aftermath of the eighth invasion, however, Ygseril died. Since then, the Eborans have suffered a long, inexorable decline.
Tormalin the Oathless abandons the remnant of once-great Ebora for a life of adventure and debauchery abroad, in the service of Lady Vincenza “Vintage” de Grazon. Vintage is determined to discover the true nature of the invaders and possibly a way to reverse the corruption each invasion leaves in its wake.
Vintage’s archaeology is surprisingly combat-intensive.
