Zoe Robinson is tired. After twenty years of marriage, her husband left to find himself, but all he found was that he didn't want to be a husband or father anymore.

Devastated, Zoe has spent the past two years picking up the pieces of her life and starting over. Her children are giving her grey hairs, her house is falling apart, and her catering business isn't enough to pay the bills. Zoe's always been resilient, but thank goodness for chilled wine and best friends, because forty doesn't look so fabulous.

Their weekly girls' nights are what keep her grounded.

At one time, sleeping in the middle of the bed terrified her, but now she's come to like it. Her feet might get cold, but there's no risk of her warm heart getting broken again. Until she meets the charming, younger Dr. Chaz Anderson, who is more than willing to help with an offer she's finding hard to refuse.

Zoe must decide whether to stay in the middle or choose a side and let someone in.
