Eleanor Oliphant Is Completely Fine by Gail Honeyman
Five Stars
Just get past the first chapter (try not to laugh!) and the rest of the book is a pure eccentric delight. Honeyman's characterization of Eleanor is believable and poignant as well as dead-pan humorous and winsome. I listened to this one on Audible, but would recommend earbuds for that first chapter and a bit of vulgarity that somehow sounds better with an English accent.
