The Onyx Sector Adventure series is Craig A. Hart’s most recent spy fiction offering, with seven books published in rapid succession in 2025 and 2026. The titles riff on famous spy movie names: Never Spy Alone, For Spy Eyes Only, You Only Spy Twice, and others, giving the series a tongue-in-cheek quality.
The fast publication pace and playful titles suggest lighter spy adventure fare compared to Hart’s more serious Shelby Alexander thrillers. The series follows operatives in the Onyx Sector through a mix of espionage and action.
