Flagstaff, 2010. A string of murders rattles the quiet mountain town. The victims share no clear link, and as fear spreads, so do uneasy questions about motive.

Reporter Miles Harper is on probation at the Flagstaff Gazette. Scrambling to keep pace with a rapidly changing newsroom, he knows that cracking the story may be his last chance to keep his career alive. But every lead drags him deeper into a tangled web of violence, extremism, and unstable suspects.

The killer is watching, close enough to strike again. Meanwhile, newcomer Maddy Sullivan is fighting her own personal battle. As she crosses paths with Miles, the two form an unexpected friendship that offers both of them a fragile sense of safety.

Together with detective Luis Ortega, can they connect the threads and bring the killer to justice?

Set against the peaks and pine forests of northern Arizona, MARS HILL MURDER is the first book in the Flagstaff Mysteries series by Mary Tolan.
