Gone Away (Circles #4)
Elizabeth Noble

Several years later Mason and Riece are thrown together once again. Riece takes a job as a US Forestry Service photographer and Mason, a park ranger, is assigned to guide him around the Black Hills of South Dakota and Wyoming. They’ve both regretted that their relationship ended and now they’re given a second chance at the love they shared.
Nothing is ever easy.
Just when Mason and Riece begin to work things out and come together again they find themselves the prey of people who hunt humans. In a desperate race for their lives they have to depend on one another like never before and that means taking a big step out of their personal comfort zones. Can they work together, survive and rekindle their love?
