The dissimilar Sullivan twins attempt to fit into their new neighborhood in different ways, but both become involved in a "war" with the bratty neighboring boys Grade 4-7-- Kitty's recently divorced mother now works, so she and her brother and sister come home to an empty house. Kitty devises a plan to get Babba, her mother's mother, to come from Florida to live with them, but since their house is so small, they need to build an apartment above their garage. The Zoning Board rejects the proposal, so Kitty attempts to get them to change their decision. A sub-plot concerns the sisters' antagonism (and finally friendship) with twins Bart and Brett, next-door neighbors who are always double-daring them. A cross between Greene's Double-Dare O'Toole (Viking, 1981) and Conford's Me and the Terrible Two (Little, 1974), this story has well-defined main characters. The resolution of the plot is not believable, but this light, rapid-paced, easy-reading story will be enjoyed by intermediate-level readers . -Bonnie L. Raasch, C. B.
