A Three Dog Life and Safekeeping by Abigail Thomas.

Both books are memoir and her latest one, A Three Dog Life, consists of essays about rebuilding her life after her husband is hit by a car. (Stephen King calls this book the best memoir he ever read.)  An earlier book, Safekeeping, is written more like snapshots, some chapters no longer than a paragraph or two.  Both books are so beautifully written that the writing seems invisible, and you can also learn a lot from the two different ways she structures them.
