Here is a beautifully written baseball book that might appeal to sports non-fans. Of course, baseball fans will love it that much more.
The Girl Who Threw Butterflies tells the story of eighth grader, only-child Mollie Williams and her attempt to play on her school's all-boys baseball team. Mollie has recently lost her father in a single-car accident, an "accident" she suspects might have been a suicide. Mollie shares a love for playing baseball with her late father, and possesses a "secret weapon" taught to her by him. Mollie can throw the impossibly difficult knuckleball pitch, sometimes called the "butterfly ball."
Best friend and budding feminist Celia convinces her to try out for the team, and motivates Mollie with true tales of women who have competed against professional male players, including the tale of Jackie Mitchell, who struck out Babe Ruth in the 1930s: "None of that All-American Girls thing with Madonna and Geena Davis," Celia tells her. While supremely self-aware Mollie struggles to keep the memories of her father alive, her mother undermines the effort by trying to eliminate all household traces of him, including items that Mollie treasures, such as her father's old baseball mitt.
Here lies the true conflict at the center of the story, that between Mollie and her mother:"Things had gone missing... it was a gradual, invisible, but profound disappearance, like erosion. The surface of the earth being transformed. But this was worse, really--it was intentional. It was thievery." Excellent inner dialogue captures Mollie's insightful views about her mother, and about her own life, in general. If it sounds too heavy, it's not. The book provides plenty of sports action, school humor, and baseball lore.
Another baseball themed book that may appeal to sports non-fans is Bette Lord's In the Year of the Boar and Jackie Robinson. This one tilts towards historical fiction. If anyone knows of other books featuring girls playing baseball feel free to post a comment.
