I have written the Annie Seymour and Tattoo Shop mystery series. The first Annie Seymour book, SACRED COWS, won the Sara Ann Freed Memorial Award for best debut mystery in 2005. The fourth Annie Seymour book, SHOT GIRL, was a Shamus Award finalist.

The Black Hat Thriller series includes HIDDEN, SHADOWED, BETRAYED, and VANISHED, all of which are available in the UK and the US in print and ebook.

The Hartford Books Examiner says that “HIDDEN is a gem of a novel in which Olson—previously limited by the confines of the cozy genre—emerges as a powerhouse thriller writer,” and Kirkus calls the Black Hat Thrillers “an electrifying series.”
