Bunny Mellon, whose life was marked by astonishing good fortune as well as tragedy and scandal, remains a singular figure in the annals of American design. She had her finger on the pulse of American culture and possessed a rare sense of style and grace. Her most celebrated work—the White House Rose Garden—demonstrated how formal restraint and the sparing use of color could be deployed to maximal effect.

In I'll Build a Stairway to Paradise, Mac Griswold—who knew Mellon personally—delves into her subject's closely-guarded personal archives to construct an unrivaled portrait of a woman as complex and multifaceted as the gardens and homes on which she left her mark. This book explores the tension between Mellon's idea of herself as a "poor little rich girl" and her own enterprising spirit. Mellon tested the anodyne 1950s model of woman as-wife-as-mother by getting a divorce, admitting candidly to her first husband that she wanted a richer one. She imperiously traded old friends for new, and ultimately used her reputation, her connections, and above all her money to help fund John Edwards's short-lived presidential campaign.

How Mellon's character, style, and taste developed together to produce her greatest accomplishments—private and public—is the real subject of this biography.
