The lemonade war

In this graphic novel adaptation of Davies' 2007 book, hurt feelings propel an intense business battle. Fourth grader Evan can't stand the thought of his brainy younger sister, Jessie, skipping a grade and joining his class this fall. Intelligent but emotionally immature, Jessie sometimes misses social cues and wishes she could be more like the gregarious Evan. These insecurities set the stage for a contest to see who can raise the most money selling lemonade this summer. Will Jessie's book smarts beat Evan's people skills? The beauty of this story lies in how each sibling's strengths rub off on the other: Evan brushes up on his math, while Jessie tentatively makes a new friend. De la Vega's polished cartoon artwork creatively translates Davies' metaphors to a visual medium. When the author compares the "mean words inside Evan…fighting to get out" to bats, illustrations depict the furry animals emerging from beneath his shirt; Jessie's negative thoughts take the form of a tiny purple creature irritatingly tapping her shoulder. Tender scenes depict flashbacks of the siblings supporting each other through their parents' divorce. The book has business savvy to match the emotional beats (each chapter opens with an entrepreneurial definition that relates to the plot), and several scenes feature math problems that readers can solve for themselves. Evan and Jessie appear white; both have friends of color. A classic sibling rivalry tale that still satisfies to the last drop.
