As small children, they watched their grandfather become president; just twelve years later they stood by their father's side when he took the same oath. They spent their college years being trailed by the Secret Service and chased by the paparazzi, with every teenage mistake making national headlines. But the tabloids didn't tell the whole story of these two young women forging their own identities under extraordinary circumstances. In this book they take readers on a revealing, thoughtful, and deeply personal tour behind the scenes of their lives, with never-before-told stories about their family, their adventures, their loves and losses, and the special sisterly bond that fulfills them.
