Dr. Leah Andrews and Jack Hobson Thrillers Books in Order

The Dr. Leah Andrews and Jack Hobson Thrillers are big, fast adventure novels with one foot in archaeology and the other in science fiction. Across the three books, Kevin Tinto sends an archaeologist and a mountaineer into a mystery that begins in the American Southwest and expands all the way to Antarctica. If you like hidden history, dangerous travel, and rising geopolitical stakes, this series knows exactly what kind of ride it wants to deliver.

It starts with Dr. Leah Andrews, who uncovers a long-abandoned Native American cliff dwelling in New Mexico. Inside, she finds evidence of violence and strange crystals that should only exist in Antarctica. That discovery forces her back into contact with Jack Hobson, her estranged husband, whose climbing and expedition experience makes him the one person who can help her reach the ice. Their history gives the series a personal thread underneath all the action.

Then the scale jumps.

What begins as a buried historical puzzle turns into a race involving governments, military teams, and a discovery under the Antarctic ice that could rewrite more than one chapter of human history. Later books widen the story with ancient survivors, advanced technology, and a destructive anomaly that keeps the pressure high. Leah wants answers, but she also wants to protect the people caught inside the mystery. Jack is often the one who has to keep everyone moving when plans fall apart.

Setting matters a lot here. The Southwest gives the series its first sense of deep time and buried secrets, while Antarctica brings isolation, brutal weather, aircraft logistics, and the constant feeling that help is very far away. Tinto leans hard into the physical side of these places. You feel the cold, the altitude, the danger, and the effort it takes just to stay alive long enough to solve anything.

These are not quiet puzzle books.

The tone is high-stakes thriller, with a strong adventure pulse and a clear science fiction edge. There are conspiracies, survival problems, special operations pressure, and plenty of moments where the books ask what happens when one impossible discovery lands in the middle of real-world power politics. Even when the ideas get large, the series keeps returning to Leah and Jack, who work best as a team when everything around them is spinning out. This is a series to read in order. Ice opens the door, Ice Genesis pushes the mystery wider, and Ice Revelation brings the trilogy to its biggest confrontation.
