When Lisa's husband leaves her for Gemma - a local beautician years younger - she's upset but nowhere near as devastated as she thought she'd be. Her marriage to David hasn't been great for a long time, never helped by his constantly roving eye.Now that he's gone, Lisa and her fifteen-year-old daughter, Susan, are left on their own at home. But Susan is a complete daddy's girl and likes to spend all her weekends in his new modern apartment that Gemma owns. Susan still thinks David is the greatest father on earth and Lisa has no intention of ruining that illusion for her daughter. In addition, Susan and Gemma have a fantastic relationship. In fact Susan says, they are as close as 'sisters', and constantly refers to the fact that 'Gemma just gets her.' And, of course, Susan and Gemma Snapchat their every waking moments.But when Susan then decides to spend the whole summer with her dad and Gemma, Lisa is devastated. She needs a change, and some time for herself. With her grandmother's legacy, she decides she needs a complete change of scene, on her own, and a run down cottage in Cornwall looks like the perfect solution.At least for the summer it's a new location, new people and a project to keep her busy. Then, when she bumps into a client she's worked with but never actually met, it's like being hit by a bolt of lightning. But can she ever have what she wants most in the world, a whole new relationship with the most important person in her life - her daughter?
