Prey by Linda Howard

Dare Callahan and Angie Powell are competing wilderness guides. Angie has been having to struggle to make ends meet and now faces selling the business, but she doesn't really want to sell to her competitor Callahan who she hasn't been on friendly terms with anyway. When a repeat client books a trip for himself and a business client to bag a bear, Angie is grateful for the business, but leery of the men. Arriving at the campsite on horseback Angie looks for bear sign. Discovering a hiker that has been mauled to death by a bear, she wants only to get out of there and notify the authorities. The two men have a different agenda. During a hard rain storm, she hears the men arguing and witnesses the murder of one. Howard writes an exciting tale, full of adventure and page-turning suspense. A good read.
