Reject by the Trial Alpha Mate

Fate can be cruel. One moment you're the beloved daughter of a powerful Shadow pack Alpha, and the next, you're an orphaned lone wolf. Then, before long, you become the mate of the alpha heir.
Lyra Nightfall thought her arranged mating bond with Dorian Blackthorne, heir to the Silver Moon pack, was just a four-year political contract. She never expected to fall for the cold and ruthless Alpha who treats her like nothing more than a burden he's counting down the days to reject.
But Dorian harbors a deadly secret—the Eclipse Curse that threatens to destroy him with every transformation. Only his supposed fated mate, Seraphina Crimson, holds the key to his temporary relief. What he doesn't know is that Lyra possesses the rare healing abilities that could be his true salvation.
With the full moon rising and ancient pack enemies closing in, can Lyra break the curse that's slowly killing the only man she's ever loved? Or will fate force her to watch as Dorian chooses her enemy over herself?
