From Publishers Weekly

In Maberry's audacious third novel featuring Department of Military Science agent Joe Ledger (after The Dragon Factory), Joe must stop a cult bent on overthrowing the world order. Though Ledger is unofficially retired, a terrorist attack that levels the Royal London Hospital killing thousands compels him to return to action. The London tragedy proves to be just the opening move in a meticulously planned plot. When a viral research facility in Scotland is compromised, the Bombay Stock Exchange is bombed, and Ledger himself is almost killed by assassins, he and his DMS cohorts quickly realize that they're up against a terrorist group with virtually unlimited resources—about which they know little except its name, the Seven Kings. Powered by a cast of over-the-top characters, breakneck pacing, nonstop action, and a subtle sense of humor, this is an utterly readable blend of adventure fiction, suspense thriller, and horror.

Following The Dragon Factory (2010), Maberry cranks up the intensity level once again with his new Joe Ledger thriller. A London hospital explodes, killing thousands. This act of terrorism is only the beginning as the group behind the explosion turns to bioweapons in an effort to unleash a modern version of the biblical Ten Plagues of Egypt. Ledger, beaten and distraught over a heartbreaking loss, has quit the antiterrorism business but reluctantly must jump back into the game, charged with nothing less than saving the world. As events unfold, allies prove to be traitors, and traitors become allies. To throw off the authorities, the terrorist group begins utilizing civilians to handle the dirty work. The publisher bills the novel as horror, but the story, horrifying as it is, definitely belongs in the thriller camp. It�s also Maberry�s best book to date. The ending guarantees a sequel that will be anxiously awaited by series fans. --Jeff Ayers
