Deadly Commitment — Kathy Harris

Danni Kemp fears she's being stalked―but the truth is much more deadly. Her new fiance, Robert Evans, has a dangerous secret. The homeless man who is stalking her, Caleb, may prove to be her only escape from a hidden world of crime. Will she discover in time that neither Robert no Caleb are who they appear to be and the one person she fears may be the one person she needs to trust? 

The Deadly Secrets series drops the reader into the frightening world of illicit drugs, where ordinary lives are lost, and families are changed forever―and in a setting so commonplace you will wonder if you or someone you love could become the next victim.
