Rick Nash as survived the nuclear holocaust. He's watched his wife die of cancer, then a series of allies that help him survive as he makes his way across the countryside. What has enabled him to survive is an entity, a living thing created from the radioactivity, that demands a human sacrifice every full moon. And as long as he obliges and finds the sacrifice, it protects him and his friends. Along the way they encounter all sorts of mutated creatures, from the radioactive "Children" to more "Resident Evil"-type monstrosities. It has the feel of a 70's or 80's apocalypse movie. It's a full-throttle end of the world book.
As with Stephen King's THE STAND, there's a showdown between Rick's people and a creature he calls the MEDUSA, that wants worldwide death through the form of a horrible virus called EBOLA-X. But this showdown is with two evil entities, neither of them good.
This is only the second novel I've read by Curran (the first was LEVIATHAN) and again, he did not disappoint. In fact, he just joined the list of Richard Laymon, Edward Lee and Jack Ketchum, as among my favorite horror authors. Highly recommended.
