The order the books were released — the default way to read the series.
Rachel Hatch is a former Army interrogator attached to an elite Green Berets team, now working as a Wyoming-based investigator whose military intelligence background and physical toughness pull her into cases far bigger than they first appear -- corrupt officials, environmental cover-ups, human trafficking rings, and conspiracies that reach into federal agencies. L.T. Ryan created the character with police detective and fellow thriller novelist Brian Shea, whose own procedural background shapes the series' investigative texture, and the two have co-written nearly every full-length entry together since the series launched in 2019.
Each book is titled after a natural-disaster or extreme-weather term -- Downburst, Firewalk, Whitewater, Tsunami -- which doubles as a loose thematic signature for the danger Hatch walks into. The series has grown into one of Ryan and Shea's most commercially successful joint projects, running to fifteen novels by 2026 with new installments still arriving roughly twice a year.
L. T. Ryan wrote the series; books 1-15 were co-written with Brian Shea; book 10 were co-written with Fiona Ryan.
L.T. Ryan co-writes the series with Brian Shea for almost every entry. One book, Fastrope (2023), was co-written with Fiona Ryan instead of Brian Shea.
