Missing in the Desert — Dana Mentink

Five years ago, her sister disappeared…
Now someone is coming for her.

Who would believe that Mara Castillo's sister -- missing and presumed dead -- suddenly sent a one-word text? Now Mara wants answers, even if it means stepping into a killer's sights with her brother's best friend, rancher Levi Duke, as her only protection. But with someone who has everything to lose after her, uncovering a long-buried secret could save her life…or claim it.
