This book is super good! It is really funny and it is for both boys and girls. It is about a kid and his friends who go on a class trip to Washington D.C. They see guys on the plane who are acting weird and think they are planning something really bad. So they try to catch the guys and it turns out to be a lot more trouble than they thought! I thought that the author did a very good job with using not too many or not enough details.
I recommend for grades:5th-8th
