Mary Anne Clark is a 31-year-old struggling waitress and soon-to-be-divorced mother of five, who serves 65-year-old Laurens Morgan Hamilton, heir to J. P. Morgan and Founding Father Alexander Hamilton. He returns the next day—her day off—to announce he’s going to marry her. She tries to dissuade him, but Laurens courts her and her five children, offering fancy meals, lavish gifts, and extravagant trips.

More than a memoir, Mary Anne’s unbelievable life stories segue to three sections of 90 Hamilton facts: Laurens’ Lists A, B, and C. QR Codes link to her online resources. Over 70 images, most in color, are posted next to their related true stories, which are entertaining and inspiring as well as challenging. These tragedies and triumphs—and an unprecedented global phenomenon when Mary Anne is in her 80s—create an unexpected purpose for her life.
