This book bundles Summer Heat and Younger Than Yesterday
Summer Heat (Cat's point of view)
When Cat is unceremoniously dumped by her girlfriend right before their holiday, she decides to join her parents on their annual trip to Tuscany. Prepared for two weeks of sun-drenched melancholy, she finds much more than nostalgia in the house where she used to spend her summers as a child.
Younger Than Yesterday (Rose's point of view)
Rose's husband died seven years ago, but when she welcomes an unexpected guest in her Tuscan holiday home, she's forced to remember what instant desire feels like. Desire for a younger woman no less.
