The Breaker of Stars by Nicole Platania

A war of fractured hearts.
A fate written in the stars.

Cypherion does not love recklessly, but he loves hard. And while his friends may have forgiven Vale’s betrayal following the Battle of Damenal, he has kept the Starsearcher at arm’s length.
That is, until his Revered commands the two embark on a quest to Vale’s territory in order to find the secrets hidden within her damaged magic. And with so many betrayals being exposed in her life, Vale has one goal: win him back, even if only as a friend.
With weeks alone, under the watch of no one but the stars, will Cypherion be able to continue protecting his heart, or will he find a fate that outweighs the risks of love? And if he does, will the eddies of war allow him to keep it?
