The new dolphin at the aquarium, Ripple, is surprised that no one will play with her. No one plays or has any fun at all, because of Snark and his shiver of sharks. At first, Ripple is intimidated by their bullying, but her trainer reminds her that happiness is a choice, and that we can each make the world a better place because of who we choose to be. Choosing to have fun, Ripple challenges Snark to a staring competition--if she can make Snark smile, Ripple wins and everyone gets to play. If not, Snark's no-fun rules will rule. Will Ripple's smile be enough to save the day?

What effect does YOUR smile have? The author of the national bestseller, The Happiness Advantage, Shawn Achor spent over a decade at Harvard University studying happiness. While he's been widely published, his research findings have never before been shared with children. Inspired to do just that, Shawn partnered with his sister, Amy Blankson, to get this valuable information into children's minds early, so the next generation can understand--and harness--the power of positive psychology. The result is Ripple's Effect, winner of The Mom's Choice Gold Award.
