Love Begins by Teresa Slack

Abandoned by their parents, Michelle Hurley and her kid sister Nicole are reminded every day their livelihood depends on a grandmother who never wanted them. Nearly twenty years later, Michelle has accepted the fact she isn’t worthy of the love she so desperately needed as a child.
Her comfortable, albeit lonely, existence comes crashing down the morning Nicole abandons her two young children under Michelle’s lilac bushes. Michelle doesn’t want to be responsible for fixing Nicole’s mistakes. Again. Nor does she want to admit she may be just like the grandmother she can’t forgive.
When as old boyfriend re-enters her life, Michelle is reminded nothing has worked out the way she hoped it would. Kyle Swann also makes her realize shutting her heart against the world could be the worst mistake she ever made.
