Welcome to my website! I am a retired rocket scientist turned writer who likes to mingle science fiction and mystery with a strong element of action thriller and a touch of romance. My style has been described as, "Hard-edged SF that wraps a compelling mystery around 'this is the real thing' space science...tight, tense, and gripping---Osborn tells a damn good story, and tells it well."
~ Holly Lisle, author of The Ruby Key: Moon & Sun I

My very first book, Burnout: The mystery of Space Shuttle STS-281, "is a compelling, impossible to put down, first novel in the class of Skylark of Space or 'Lifeline'...It may perhaps be the most realistic view ever published in fiction about what happens behind the scenes at NASA."
~ Jim Woosley, Ph.D. physicist and Heinlein essayist

My Displaced Detective books "are like literary crack. I fell in love with [Osborn's] characters and her world so completely that I’ve been telling all my friends ‘YOU MUST READ THESE!’ And yes, I’ve been doing so in all caps."
~ Melissa A. Bartell, Bibliotica

About the new Division One series, "This [is] Stephanie at the top of her form...a master of her craft...I was spellbound."
~Daniel Hollifield, Editor in Chief, Aphelion Magazine
