** I read an advance reader copy of this book I won through a Goodreads giveaway. **

This is a very enjoyable, fast-paced action novel perfect for middle-grade readers. It's timely in that it describes the aftermath of a new, flu-like virus that decimates the population and forces survivors to live their lives enclosed in apartments, with no (easy) way to leave. The main character goes on an adventure to deliver medicine to another resident of her building after it is delivered to her apartment by mistake. The description of her journey through the building and outside the building are well done and, as I stated, the action is well paced and quick enough to keep even reluctant readers going. The ending was a bit of a surprise and was believable enough to make a satisfying solution to the story. I enjoyed this very much!
