This book series is SO good. It kept me glued to the page, and always wanting more. I watched the movie before i read the first book, so i already kind of knew what to expect. But the first book went into so much more detail than the movie ! The second book took awhile to liven up, but once it did, i couldn't put it down. I have yet to read the third book, but i have read that it is going to be just as great as the first two.
These books are great for teens or adults. If you love post-apocalyptic sci-fi novels, then these are for you !
