The Obsidian Files Books in Order

The Obsidian Files takes Shannon McKenna's romantic suspense and pushes it toward techno-thriller territory. The core idea is wonderfully pulpy and surprisingly grounded at the same time: years ago, runaway teenagers were swept into a secret research program funded by the Obsidian Group, a cabal of ultra-rich power brokers trying to engineer something beyond ordinary human ability. Brain stimulation, implants, gene modification, cybernetics, all of it got used on kids no one expected anybody to miss.

The experiment worked, just not in the way the people paying for it expected.

The survivors escaped, burned the facility, and disappeared. By the time the series starts, they are adults living under deep cover, carrying bodies and minds that have been altered in ways even they do not fully understand. That gives the books a different flavor from McKenna's more straightforward suspense work. The danger is not only outside. It is inside the characters, too, in their memories, enhancements, instincts, and the fear of being found and dragged back.

The first books follow Noah Gallagher, Zade Ryan, and Luke as they fight to protect the women they fall for while trying to stay ahead of the people who made them. Caro Bishop, Simone Brightman, and Dani LaSalle are not just love interests dropped into the blast zone. Each one has knowledge, secrets, or choices that matter to the larger plot. Even when the series goes big, with conspiracies, labs, and brutal enemies, the romance stays personal and immediate.

One of the best things about this series is its tone. It has a futuristic edge and an urban fantasy vibe, but it never actually turns magical. The strange abilities, weird sensory effects, and heightened bodies all come out of experimentation and technology, which keeps the world feeling tense rather than dreamy. The books are still very much Shannon McKenna books, meaning fast pace, strong sexual tension, fierce protectiveness, and a lot of danger, but the Obsidian setup gives her extra room to get weird in a fun way.

The settings help, too. You get corporate towers, hidden safe houses, mountain retreats, and international detours, including a honeymoon in Italy that is absolutely not allowed to stay peaceful. All of it suits a series about people who can never fully relax because somebody powerful is always trying to reclaim them.

If you want romantic suspense with secret experiments, enhanced survivors, conspiracies, and a tight-knit rebel family at the center, this is a great McKenna series to try. Start with Right Through Me and keep going in order. The books are linked, the threat never really goes away, and the world gets richer as more pieces click into place.
