The next two SSYRA books that I have read are How Oliver Olson Changed the World by Claudia Mills and Bobby vs. Girls (Accidentally) by Lisa Yee. In both of these books the main characters are boys, but believe me these books are not just for boys!
How Oliver Olson Changed the World is a book about a 3rd grade boy who has extremely overprotective parents! So much so that they hover over everything that he does. When his teacher Mrs. O'Neill assigns a project Oliver may just find a way to convince his parents that he is growing up and may not need the amount of help that they think they need to provide for him. This project may even change the world . . . you will have to read to find out for yourself.
Bobby vs. Girls (Accidentally) is a story about a boy named Bobby and how his life is changed at the beginning of fourth grade. One event after another will accidentally pit Bobby against all of the girls in his class. This book is very entertaining and you will laugh page after page!
