Corporate lawyer Ava Burch has had enough of the big city. She 
grew up with her father, who raised search-and-rescue dogs, and 
has moved to Cuervo to spend time in the wilderness near Big 
Bend National Park. When she and her dog, Huck, discover an 
abandoned campsite on a volunteer search-and-rescue mission, 
she's perplexed, but she photographs it all the same. All Grant Wycoff can see 
when he looks at Ava is a city slicker who has no business on a serious team 
made of seasoned outdoorsmen and retired cops. But when she tells him of 
her findings on the trail, he sees there's more to her than meets the eye. Ava's 
discovery reminds Grant of the unsolved case of a young woman who went 
missing two years ago. As they look into the campsite further, another woman 
disappears. With time running out, Ava and Grant must work against the heat 
from both the Texas sun and their own chemistry to solve the case.
