The Trouble with Shifters and Fae Courts. Cary Redmond, #8

Trouble is Back. And taking her newfound skills on the road. Cary Redmond survived a lot in the last year. From her Seventh Year test as a magical Protector, to meeting her leopard shifter mate, to fending off a whole host of enemies. A trip to Scotland with Deacon presents a well-earned chance to rest and practice her newfound skills and powers. Even if meeting Deacon's grandmother comes in the bargain. But Trouble follows Cary wherever she goes, including all the way across the pond to Scotland.
Where Deacon's grandmother harbors a secret tie to the Fae, and rival Faery queens fight for dominion. Cary finds herself, once again, in the middle of powerful enemies, protecting everyone in the crossfire. This time, though, if she fails, the cost could be the love of her life. Because this time, Faery wants Deacon.
