Edgar nominee, Mark Schorr, introduced detective Brian Hanson to rave reviews in the novel "Borderline." Now, in this thrilling follow-up "Fixation," Hanson is back - risking his reputation and his life.

A Vietnam vet with post-traumatic stress disorder and a history of substance abuse, Brian Hanson has turned his life around working as a counselor with some of Portland, Oregon's most troubled citizens.

When an FBI raid goes badly for his girlfriend, Special Agent Louise Parker, Louise comes under investigation by the very agency she is loyal to. Louise turns to Brian for support, but a cunning stalker is deliberately sabotaging all that is precious to her. And as the harasser grows more and more aggressive, there's no telling who she can trust.

Taking readers from Portland's mysterious underground tunnels, to computer dives in Seattle, to the back streets and alleyways of the Rose City, "Fixation" offers gripping characters with a rich sense of place, and the kind of psychological insights that only a counseling professional could bring to a thriller. It is a stunning novel from a multitalented crime star.

Watch this space as reviews come in for "Fixation" and Mark breaks away from doing therapy, training and writing to publicize his new book.
