Despite, knowing where I am currently, may I suggest Audible? Once you’ve stripped the DRM you can then put it into whatever format you want. There’s a Windows application called OpenAudible, I that’s what it’s called, that I use to strip the DRM and then transcode it into MP4.
It’s not free, I know, but they seem to have almost any audiobook you might want.
