So this is definitely not a book I would normally have read. I read it for work and it's the last of the must reads for work for a little while. I had to read this as part of my job as a teen librarian but I definitely think it skews younger.
Matt lives with his mom and his sister Bonnie. Bonnie meets him everyday right after school and they take the bus home together. Until one day Matt isn't there. The tale that follows is sad and scary but packed with a lot of important information.
None of the charaters is very deep in this book. Everyone is there to tell their part of the story. The story is an important one. It's important to see how Matt was tricked and how many people saw something and didn't really realize what was going on. There is also a good description of the Amber Alert process and what goes into looking for a missing child.
This book is most definitely a cautionary tale for younger kids. There is a lot of good information here and I think that it's a good reminder to adults that children can't always take care of themselves and that even the strongest precautions sometimes aren't enough. It's also a good reminder to children to always be aware of what's going on, to ask for help and to never go with strangers
