When Noreen takes a buyout and gets dumped by a boyfriend in one fell swoop, she finds herself with nothing but time to notice everything that's missing in her life. Tess is the teacher next door who thought she'd be spending the summer with her college-bound daughter, but now that daughter isn't speaking to her. The Wildwater Walking Club is complete when they meet Rosie, the dutiful daughter who moved her family onto her parent's farm after her mother died.
