Hatch by Dale Mayer

Hatch is more than happy to step up and to rescue the missing father-and-daughter archeological duo. Now if only it were that easy. They’d been questioned by the Egyptian government and released, with a warning to not leave Cairo. But, when their hotel room is found empty, most believe they took off ahead of punishment—but not Hatch’s team.
When the father’s foreman turns up dead, Hatch investigates the body-dump location and finds the daughter, weaving through the sand, ready to collapse.
Milly is shaken and grieving. During her captivity, her father dies, and she escapes, only to find herself lost in the sand dunes. She may be safe, but her father will never come home. Millie is determined to find the man responsible for her father’s death and for the information that’s changed her entire life.
