From Keith Lee's Associate's Mind, "Review: Solo by Choice"--
[F]rom what I’ve read around the web, the general consensus for the best place for advice regarding going solo is Carolyn Elefant’s book, Solo By Choice (and her accompanying website, myshingle.com). With that in mind, I purchased a copy to see for myself.
The remainder of Lee's long post is a comprehesive review of Solo By Choice, which concludes "it's a fantastic book." (My own review of Solo By Choice, which has a similar conclusion, is here.)
