Min has just turned 16 and just like all of her previous birthdays on even years, she was murdered by the man in black. Also just like before, she wakes up in a small clearing near her home with no evidence of her death. Min has been seeing a counselor and taking a pill he prescribes for years but neither thing has stopped the murders. This year, however, Min and the rest of the world are facing something that could possibly be an even bigger issue. A huge asteroid nicknamed the Anvil will be passing close enough to Earth that there is a danger of a collision that would wipe out all of humanity. As the Earth begins to deal with unprecedented natural disasters, Min discovers that she is not alone with her problems and that several people close to her might know more about what is happening than they have revealed.
The first half of the book was great and fast-moving with a weird premise I don't remember seeing before. I couldn't wait to find out what exactly was happening. Then the second half began and I felt for awhile that I was reading some other book entirely. Something Lord of the Flies-ish. I still couldn't wait to find out what exactly was happening, but I wasn't enjoying it as much at that point and the story dragged. Finally, at the end I felt my familiar sense of being disgruntled because of the hard cliffhanger that made this book feel almost like a prequel to what's REALLY going to happen next. All of that is not to say that I didn't enjoy the book, just that it wasn't as great as I was expecting after reading the first few chapters.
