I thought War With Grandpa was a good book.It was about when grandpa moved into Peter's house from Florida.Then Peter had to give away his room to grandpa.Peter did not want to give away his room,so he went to his friends to ask what he should do.They thought he should have war with grandpa.Grandpa and peter did some pretty bad tricks to each other.I can not tell you all the things they did at the end,because that will spoil the end of the story.
