P.J. Tracy is the pseudonym of mother-daughter writing duo P.J. and Traci Lambrecht, winners of the Anthony, Barry, Gumshoe, and Minnesota Book Awards. Their first four novels, Monkeewrench, Live Bait, Dead Run, and Snow Blind have become national and international bestsellers.

P.J. Lambrecht is a college dropout with one of the largest collections of sweatpants in the world. She was raised in an upper-middle class family of very nice people, and turned to writing to escape the hardships of such a life. She had her first short story published in The Saturday Evening Post when Traci was eight, still mercifully oblivious to her mother's plans to eventually trick her into joining the family business. She has been a moderately successfully free-lance writer ever since, although she has absolutely no qualifications for such a profession, except a penchant for lying.

Traci Lambrecht spent most of her childhood riding and showing horses. She graduated with a Russian Studies major from St. Olaf College in Northfield Minnesota, where she also studied voice. Her aspirations of becoming a spy were dashed when the Cold War ended, so she instead attempted briefly and unsuccessfully to import Eastern European folk art. She began writing to finance her annoying habits of travel and singing in rock bands, and much to her mother's relief, finally realized that the written word was her true calling. They have been writing together ever since.
