The Lies of the Eternals (The Realm Weaver Trilogy) by B.B. Aspen

Threads will be frayed. Hearts will be broken. Lies will be exposed. The Woodlands Wisteria left behind swiftly became the Deadlands. The nation of Numaal rotted with corruption from the inside out, only now humans no longer accept the blindfold of ignorance and lies. Lies that have pervaded across the Thalren Mountains where the Weaver of Fates continues to intertwine Wisteria, Zander and Fennick's threads. As well as the threads of ancient mythical creatures, Eternals and rebels leaders... Each woven's resolve is tested, their character tried, their weaknesses made vulnerable for sacrifices that must be made. The runegate to the beyond threatens to shatter, leaving the Dreamer Realm, and whole of Kinlyra, susceptible to the all consuming plague. Our wovens' future is daunting and indeterminable, but as the War of Worlds commences, light is shed on their pasts and what is revealed is profound enough to rattle even the White Tower.
