YES for our library. 
 This is another great Andrew Clements book, though I don't feel it quite soars like Frindle or No Talking (which was a nominee this year). The idea of two twins making their way through the beginning of school as though they're really only one boy is a very common theme in twin books, but it works well in Clements' story. 
 Still, I would say there are probably better titles to make our top picks this year. The kids will love this book as they always love Andrew Clements' work, so I'm not worried at all about it being looked over in our library!
