Powerful wisdom for young women, in a new collection from the editor of the New York Times bestseller What I Know Now (tm) If you could send a letter back in time to yourself, what would it say? Following in the tradition of the bestselling What I Know Now (tm) comes a new collection that will speak directly to young women. Editor Ellyn Spragins asked women under forty to write letters to the girls they once were, filled with the advice and insights they wish they'd had when they were younger. Readers will recognize familiar names as well as meet new voices in these wonderfully candid missives, including: author Hope Edelman; actress Jessica Alba; Olympic soccer gold medalist Julia Foudy; activist Zainab Salbi; actress Danica McKellar; and author Plum Sykes. A perfect gift at graduation or for any important young woman in your life, If I'd Known Then offers rare glimpses into the personal stories of extraordinary young women--and will inspire readers to live their best lives.
