I realize that most folks here don't read non-fiction, but here are the two e-books I am currently reading (both Overdrive downloads):
Give It Up!: My Year of Learning to Live Better with Less by Mary Carlomagno -- a dozen essays on areas in her life she's given up for that month: using her mobile phone, eating out, alcohol, etc.; the entries aren't as self-congratulatory as I'd feared they might be. The items return to her lifestyle afterward, but they don't play as much of a part as they did given her new awareness.
The Inland Sea by Donald Richie. Author's travels through the (then remote) islands of southern Japan, before satellite television, cell phones, etc. became commonplace (c. 1970).
