Karen Rinaldi, who joined HarperCollins in March (after a stint at Rodale) to oversee a new list of health and wellness titles, has made one of her first acquisitions, buying a fitness/lifestyle book by actress Cameron Diaz. Rinaldi took North American rights in the deal from Jennifer Rudolph Walsh at William Morris Endeavor.

The book, which is scheduled for fall 2013, will be edited by Julie Will and is promised, HC said, to "offer health and wellness advice and inspiration for young women, addressing fitness, nutrition and well-being." The publisher added that the book will "engage and empower women and girls by showing them that with the right knowledge about their bodies, they can live happier, healthier, stronger and better."
