Fae of the East - Court of Crown and Compass, #4

Before twelve moons turn, else the realm will burn.  Elsie's childhood sweetheart turned out to be the scourge of Alvheim. When she has the opportunity to enter the annual Thunder Tournament, she impresses the king with her archery skills, drawing his attention-and she's not sorry. But he will be. If anyone knew the secret Asher guards, they'd understand why he rules with a fist as strong as elven iron.
He does his duty, hunting and haunting the murkast, until someone from the past threatens to expose the truth. And he's not sure he should stop them. With the future of the fae under threat, Elsie has been waiting for her sisters to penetrate the Eastlands stronghold so they can fulfill the age-old prophecy. They must embark on a journey to the library of memory, stop a war, and save the realm or grim powers will destroy them all. While Elsie and Asher each have secrets and want answers, what they really need is the truth...and that includes how they feel about each other. This is book 4 of 4, the spellbinding conclusion of the Court of Crown and Compass series.
It's romantic fantasy perfect for fans of The Cruel Prince, from the Folk of the Air series, by Holly Black as well as K. F. Breene's Demon Days, Vampire Nights world and is chock full of mystery, danger, and sizzling kisses.
