From such modest beginnings, Brown has evolved into multimillion publishing empire of one, the CEO of her own literary brand; she towers over the landscape of romantic fiction. Brown has used her growing clout to insist her publishers drop the bosom-and-biceps covers and has added more intricate subplots, suspense, and even unhappy endings to her work. The result: A near-constant presence on The New York Times bestsellers list. In 1992, she had three on the list at the same time, joining that exclusive club of Stephen King, Tom Clancy, J. K. Rowling, and Danielle Steel.

Her work in the mainstream realm has taken her readers into The White House, where the president's newborn dies mysteriously; the oil fields and bedrooms of a Dallas-like family dynasty; and the sexual complications surrounding an investigation into an evangelist's murder. Such inventions have made her a distinct presence in a crowded genre.

"Brown is perhaps best known now for her longer novels of romantic suspense. The basic outline for these stories has passionate love, lust, and violence playing out against a background of unraveling secrets and skeletons jumping out of family closets," wrote Barbara E. Kemp in the book Twentieth-Century Romance & Historical Writers . Kemp also praises Brown's sharp dialogue and richly detailed characters. "However, her greatest key to success is probably that she invites her readers into a fantasy world of passion, intrigue, and danger," she wrote. "They too can face the moral and emotional dilemmas of the heroine, safe in the knowledge that justice and love will prevail."

Critics give her points for nimble storytelling but are cooler to her "serviceable prose," in the words of one Publishers Weekly reviewer. Still, when writing a crack page-turner, the plot's the thing. A 1992 New York Times review placed Brown among a group of a writers "who have mastered the art of the slow tease."

Staggeringly prolific, Brown found her writing pace ground to a halt when she was given a different assignment. A magazine had asked her for an autobiographical piece, and it took her months to complete. Her life in the suburbs, though personally fulfilling, was nonetheless blander than fiction. That may be why she dives into her fiction writing with such workhorse gusto. "I love being the bad guy," she told Publishers Weekly in 1995, "simply because I was always so responsible, so predictable growing up. I made straight A's and never got into any trouble, and I still impose those standards on myself. So writing is my chance to escape and become the sleaziest, scummiest role."

When she started writing, her goal was always to break out of the parameters of romance. After about 45 romances, the woman who counts Tennessee Williams and Taylor Caldwell among her influences told The New York Times that felt she had reached a plateau. In fact, she doesn't even look at her books as romances anymore. "I think of my books now as suspense novels, usually with a love story incorporated," she said. "They're absolutely a lot harder to write than romances. They take more plotting and real character development. Each book is a stretch for me, and I try something interesting each time that males will like as well as women."
