Meggin Cabot was born on 1st February 1967, in Bloomington, Indiana. The intervening years of Meggin's childhood were spent in pursuit of air conditioning, of which there was little at the time in Southern Indiana. A primary source proved to be the Monroe County Public Library, where Meggin whiled away many hours, reading the complete works of Jane Austen, Judy Blume and Barbara Cartland. It was around this time that Meggin's desire to be a writer bloomed, a goal that was not forgotten, even when she fell in with a theatre crowd in high school and went on to star in productions such as The Good Doctor and Li'l Abner.

After earning a Fine Arts degree at Indiana University, Meggin moved to New York City in 1989, intent in pursuing a career in freelance illustration. Assignments by MTV and Planned Parenthood soon followed. In September, 1994, however, spurred by the sudden death of her father, Meggin dusted off one of the many manuscripts she had penned in her spare time and began to look for representation. Where Roses Grow Wild, her first historical romance was published by St. Martin's Press under the name Patricia Cabot. Two other romances followed, and then prompted by her mother moving in with one of her former art professors, she wrote both The Princess Diaries and The Meditator, books which happen to be about, among other things, teenage girls dealing with unsettling family issues.

Meg Cabot currently resides in New York with her husband and their one-eyed cat named Henrietta.
