Betty Neels - OK, she did not write high literature, but her stories are sweet and romantic. The heroines are (mostly) likeable ordinary girls, and the heroes are fabulous creatures - either Dutch or English. I have a number of favourites - Mistletoe Kiss, Discovering Daisy, Fate is Remarkable.
The storyline in this book is best suited to an audience of tween girls. There is a touch of romance between the main character, Allie, and one of her new teammates, Eric. They bond over their interests in baseball and slugs. Although there is a lot of baseball game narration in the book. . . young readers may enjoy the discussions on double standards and sportsmanship, plus the unpredictable ending.
