Orion Publishing Group The Devil's Elixir

Sean Reilly and Tess Chaykin return in an edge-of-your-seat story that reaches from the present day back to 1800s Mexico-and possibly beyond. In The Devil's Elixir, Sean and Tess find themselves in a race-against the clock, against drug kingpins, and even against the DEA - to merge two divergent trails, one several hundred years old, the other as current as a heartbeat, which together may lead humanity to the brink of annihilation.
