In England during the 1950s, teens Janie and Benjamin must use ancient natural recipes in order to concoct brews that will help them save the world from the threat of nuclear disaster. Using an international cast of characters, this young adult novel touches on post-WWII politics, but not enough to bog down younger readers. Despite the looming threat of nuclear war, many humorous interactions and situations keep the book light and fun to read. Ages 10 and up. (Putnam)
