The Last Letters of Sally and Walter by Cammie McGovern

Sally and Walter are both residents at the Golden Grove retirement community and meet when Sally comes to the Scrabble club that Walter runs. Walter happens to be the only member, but soon they are playing a game and it becomes clear that they are kindred spirits. Sally is also a very good Scrabble player, probably better than Walter, because she stays calm under pressure. Soon, Walter is coaching Sally and they find their friendship possibly deepening into something more, but both find that they have unresolved issues with their adult children that they need to take care of. Additionally, Sally's increasing Parkinson's symptoms are causing her to revert inward. Can Sally and Walter expose their true feelings and become truly vulnerable with each other? The Last Letters of Sally and Walter is a cozy story of friendship and romance similar to Major Pettigrew's Last Stand and the novels of Elizabeth Berg.
