When dragon shifter Eivross refuses his king brother's call to wage war against another nest, he chooses exile over taking innocent lives. Seeking a new home, he finds refuge in Cider Falls.

Diem loves Cider Falls and working in the bookstore, and she's even happier now that she's picked up a volunteer job at the school library. When a stranger comes to town, Diem knows he's her truemate, and not just because he shifts when they meet and rips the front door off its hinges.

But Eivross won't take Diem as his mate because his brother is dangerous and he's worried she'll be caught in the crossfire. When a jealous female dragon reveals Eivross's location, his brother arrives with an army, intending to take Diem for his own mate and kill Eivross in the process. Can Eivross keep Diem safe against an angry dragon horde, or will he lose the most important treasure of all?
