FBI agent Sean Reilly and his girlfriend, archaeologist Tess Chaykin, heroes of Raymond Khoury's bestselling Templar novels, return in another edge-of-your-seat thriller that reaches from present day back to 1700s Mexico-and possibly beyond. What if there was a drug, previously lost to history in the jungles of Central America, capable of inducing an experience so momentous-and so unsettling-that it might shake the very foundations of Western civilization? What if powerful forces on both sides of the law got wind of that drug and launched a vicious, uncompromising pursuit to possess it? In Raymond Khoury's million-copy-selling Templar novels, Reilly and Tess traveled the globe to unravel ancient mysteries with present-day ramifications. In The Devil's Elixir, they find themselves dragged into a race-against the clock, against a brutal drug kingpin known as "El Brujo"-the sorcerer-and even against government authorities-to merge two divergent trails, one several hundred years old, the other as current as a heartbeat, that could drag humanity to the brink of self-destruction. Packed with the nonstop suspense and unexpected twists Raymond Khoury fans delight in, The Devil's Elixir is destined for bestseller lists everywhere.
