This book was super cute, and although aimed at a younger audience, I still really enjoyed it.
I've actually had this book on my shelf for years and it just occurred to me that it is by the author of The Hunger Games (a series that I loved!). While I wouldn't say it's as good as those, this book was still very interesting and I look forward to reading the rest of the series.
Basically, we follow Gregor and his sister Boots as they fall out of a NYC laundry room into an underworld ruled by giant bugs, bats, and rats. They go on an Alice-in-Wonderland-like adventure as they quest to make it back home in one piece.
I give it 3.5 out of 5 stars.
