Broken Trust by Shannon Baker

When a chance meeting on a hiking trail leads to a position at a nonprofit in Boulder, Colorado, Nora feels lucky to have a job . . . even after she finds out that the previous financial director has gone missing.
With her suspicions of foul play confirmed by her Kachina guardian, Nora doesn't know who to trust in an organization that's rife with deceit and corruption. As she's pulled deeper into a treacherous conspiracy, an unannounced visit from her mother and a reunion with Cole Huntsman have Nora playing tug of war with her own feelings. Fearful for her own life and the safety of those she loves the most, Nora wonders if her new beginning in Boulder will turn out to be a deadly mistake.
Praise:
"Baker deftly escalates the stakes of her initially straightforward story, which takes a much more serious turn before arriving at its unexpected conclusion." -Publishers Weekly
