I really like Mr. Lemoncello’s library series because of the humor and action in it. When Kyle’s team runs to the finish line and Charles is really mad, it’s really funny. Chris Grabenstein really puts a lot of detail, and I can picture it happening in real life. There are 4 books in this series and the picture on the top is the second book which is the one I am on. I would rate this series 5/5 stars because of the plot twists, for example, in book 2, near the end Mr. Lemoncello stops the challenge and in the end, Mr. Lemoncello was faking the whole thing!
