Karen and I joined Audible to get a free audiobook to listen to on a road trip. We chose "Zen and the Art of Motorcycle Maintenance", which we're still enjoying. As Audible counted on, we never canceled and have been billed monthly for about 6 months, accruing 6 credits. When I went to cancel, they warned that all unused credits are lost, though any books downloaded remain your property. So...looking for suggestions. Into science, science fiction, tech, history, whatever. Considering "Ready Player One" and "American Lion", Meacham's biography of Andrew Jackson. Already read "The Wright Brothers" by McCullough. Open to any and all suggestions!
