Harriet accepts her friend George's challenge to ride the frightening roller coaster, and finds out that she is the brave one.
"Carlson's winning, childlike illustrations use minimal line work to evoke her characters' extreme emotions (George's taunting nature is depicted by the slightest slant of an eyebrow). More expansive elements, such as the loop-de-loop of the roller coaster, are also drawn with understated flair. Children will be encouraged to brave new adventures, even if they're scared, and learn not to be swayed by those who claim they're not." -- Booklist
