An Emergence of Green by Katherine V. Forrest

Carolyn Blake appears to have the perfect life as the wife of a successful businessman, but everything begins to change when she meets her new neighbour, artist Val Hunter. Their friendship awakens feelings Carolyn has never experienced and causes her to question her marriage and the controlled life she has always accepted.

As Carolyn grows closer to Val and begins seeking independence, her possessive husband sees their relationship as a threat and becomes determined to keep Carolyn firmly under his control.
