Meet Zero, whose previous name, Patient Zero, has long been forgotten. Before he had that name, he was a scientist called Tim Fanning who went on an expedition to Bolivia and came home with a virus that changed everything. When you pick up this huge book that spans places all over the world, and enough time to follow generations of characters, you get to find out what happens after a top-secret military project tried to use Zero's illness as a weapon, and also what happens to the people he meets and infects along the way -- their everyday, horrifying, and heroic stories will surprise you.
Now that the second volume of Justin Cronin's trilogy is out, this is the perfect time to pick up The Passage and catch up. (The new one's called The Twelve.) If you're a fan of epic-length genre fiction that straddles horror and sci-fi, like Stephen King's The Stand, or Robert McCammon's Swan Song, you'll love Cronin's blend of action, world-building, and his carefully-thought-out take on vampires (don't worry, it's nothing like Twilight).
