My second read for the Postal Book Club v. 2.0 was The Storied Life of A.J. Fikry. It was E's pick, and it was a great one for vacation; it was more than a beach read but not a downer. In the description I shared with K and E, I overused the word "charming," which is still the best descriptor I have for it.
The title character is the owner of a bookstore on a small, relatively isolated island. As such, the cast of characters is small and, though flawed, they are winning. A.J. is a widower and loner, and his few reliable people are as much his rescuers as his friends. The plot is simple and human and . . . charming. I won't say much more about it, because I would have to give away a relatively early plot point, so you'll just have to read it!
As you all know, I'm a slow reader. Even though I read this on vacation when I had the time to devote to a novel, I think it would have been a quick read even in real life. It's especially delightful and fun to read if you are a fan of bookstores!
