Cold Granite, the first Logan McRae mystery
by Stuart McBride, is currently $0.99 at
Amazon US.
($4.99 at B&N, Kobo, and Google.)
FYI, I just finished reading this a week ago and thought it was very good. Well-written, atmospheric, suspenseful, but
not for the faint of heart. I've already added the next in the series to my TBR pile.
