Gary Gerlacher’s AJ Docker series has grown to six books since its debut with Last Patient of the Night in 2023. The titles lean heavily into thriller territory: Faulty Bloodline, Sin City Treachery, Deadly Equation, Terminal Exchanges, and Phantom Files all suggest a series built around suspense and danger.
Gerlacher has kept up a fast release pace, putting out multiple books per year. Three books landed in 2024 alone, with the series continuing into 2025 and 2026. If you’re looking for a newer thriller series that you can binge from the beginning, this one has enough books to keep you busy without a decades-long backlog to catch up on.
