Blue hardcover mystery novel with sunburst motif

I lost my blue hardcover mystery novel yesterday around 3pm near the Flagstaff Public Library on West Aspen Ave, by the fountain outside the front doors. It's a 2014 hardcover edition, blue cloth cover with a sunburst design on the front, dust jacket a bit worn around the edges. Inside cover there's a pressed lavender sprig and a tiny coffee stain along the bottom edge. It was a gift from my grandmother and has sentimental value, so I’d really appreciate getting it back if you find it.
