Twilight Echoes by Jen Talty

A ballerina’s nightmare…
A choreographer’s curse…
And a deadly spell destined to destroy true love…

Lady Avery Windsor knew she couldn’t be the lead ballerina forever, but she never expected her position to be challenged by a legend that would change the fabric of her life. To make matters worse, the new wolf choreographer, Darrell Hughes, brings with him a curse. One that could destroy his pack and flip her and sister’s royal destiny upside down.
Darrell Hughes took the job with the local ballet for one reason, and one reason only: to find a way to save his pack from being wiped off the earth by a black magic spell. Avery’s father is the only one who can help. The fact that he’d imprinted on Avery years ago, claiming her as his mate, would have to take a back seat. That is until he learns he and his mate are more than fated.

They are the second paring of the Legend of the Fated Moons.
