@bigeck11For Coming of Age, definitely check Michael Loucks' A Well Lived Life.
My own Variations on a Theme series is a blend of Coming of Age and Do-Over (and, of course, is slowly becoming Alternative History, almost by definition).
My one hesitation in blowing my own horn is that Book 1 (in particular) is long in the tooth and I, along with my editors, am working on a major repost; it might not be the ideal time for a new reader to jump in. Or, possibly, I could send an advanc reader copy of the updated Book 1 :) With one exception, no significant plot changes, but many, many clean-ups. It's fine as published, but much better in the updated form.
