Cave of Secrets
When Carli Moore finds the body of Zain Wescott's missing sister on her family's ranch, Zain is convinced Carli's brother is the murderer. But Carli's sure Zain is wrong, and she'll prove it - if the killer doesn't take out both her and Zain first. Now they just have to live long enough to uncover the truth...and bring a murderer to justice.
Carli scanned every superficial detail, but no other clues to what was underneath presented themselves. She knelt onto the cavern floor. Moisture seeped through the fabric of her riding pants and her fingers shook as she reached out, knocking a couple of stones away. Their clamor a soundtrack to the horror unfolding before her.
A human skeleton.
