Edge of Evil (Ali Reynolds #1) by J.A. Jance
Ali has lost her job, her marriage, and her best friend all in a few days. The job and marriage are a wash due to replacements with younger women, but her friend’s alleged suicide does not ring true. Ali moves home to Sedona, Arizona and with the support of her family and friends starts an investigation of her own into her friend’s death.
A good, but predictable ending.
