Children of Evolution (The Gateway Series)

"It's got to be hard to keep amazing coming and coming in each chapter, but Toby set the standard with his first novel and this one stays true to form."

With her world turned inside out, Nikki is struggling to feel anything besides useless and alone, even though she and Michael are closer than ever. Her first instinct was to curl up and hide, but four months of feeling sorry for herself was three and a half months too many. Her world clearly isn't going to fix itself, so she's taking over. Now she's hitting the streets every night, searching for something—anything—to make her feel like her old self again. But what she finds is a nightmare. A vicious new threat is prowling the shadows, a herald of the coming apocalypse—a threat that might be closer to home than anyone realizes.
