1. Old Bones

Old Bones (2019)[7] introduces the central pattern of the series: an archaeological mystery whose historical evidence intersects with a modern criminal investigation. Nora Kelly becomes involved in the search for a lost Donner Party site, while Corrie Swanson investigates related grave robberies.[2]
This novel establishes their professional connection and gives the series its blend of field archaeology, forensic inquiry, and historical danger.[2]
2. The Scorpion’s Tail

The Scorpion’s Tail (2021)[8] brings Corrie and Nora together again through a case involving a mummified body, a radioactive discovery, and a buried Spanish colonial treasure. This book is a separate investigation, but it benefits from the established Nora-Corrie partnership.[3]
It also continues Corrie’s development as an FBI agent and places Nora’s archaeological work within another high-stakes historical puzzle.[3]
3. Diablo Mesa

Diablo Mesa (2022)[9] shifts the series toward Roswell, a controversial excavation, and evidence tied to a 1947-era mystery. Nora’s professional position becomes part of the setup, while Corrie’s investigation intersects with a secret involving the site.[4]
This novel is readable on its own, but it gains context from the recurring characters, Nora’s family connections, and Corrie’s FBI role.[4]
4. Dead Mountain

Dead Mountain (2023)[10-11] centers on a cold case in the Manzano Mountains after modern remains are found in a cave containing older archaeological material. Corrie works with a new FBI mentor, while Nora’s expertise helps connect the physical evidence to the site.[5]
This book continues the series’ pattern of present-day investigation rooted in hidden history and adds further continuity for Corrie, Nora, Skip, and Sheriff Watts.[5]
5. Badlands

Badlands (2025)[12-13] follows a new investigation into deaths in the New Mexico badlands connected to rare ceremonial stones, academic history, and remote archaeological sites. Nora and Corrie again combine archaeological knowledge and federal investigation, with Skip and Sheriff Watts also drawn into the case..[6]
It reads as a standalone mystery while rewarding readers familiar with the recurring relationships and prior developments.[6]
