With a Twist (Swizzle Stick Romances 3) by Georgia Beers

Amelia Martini is rebuilding her life after her wife leaves, facing middle age alone and trying not to grow bitter. Kirby Dupree, an interior painter who has survived her own losses, chooses to look for beauty even when it is hard to find. Their first meeting is rocky, with Amelia finding Kirby too cheerful and Kirby seeing Amelia as far too serious. Forced to work together, they begin to see past their first impressions and prove that opposites can attract. The real question is whether they are brave enough to reach for the love they both deserve.
