Through the Fire (Love on Fire #4)
Cherie Summers

Annette Hall, Adrian’s cousin and Melody’s best friend, has left her unfaithful husband and is building a new life for herself and her three sons. In Kat, she sees a gorgeous man with a good heart. One who’s always been there for her even when her husband was not. As the two of them begin to look beyond the boundaries of friendship, they start to see the possibility of a relationship that could last a lifetime. There’s just one problem…her husband wants her back.
Despite all his failures as a husband and father, Dr. Adam Bryant promises Annette they can pick up the pieces and put their family back together. But when his wife repeatedly refuses him, something snaps, and a dark, sinister side of Adam emerges—a side willing to destroy every relationship Annette has ever had and hurt everyone she loves, including their sons.
