There's a "
coming of age" book by Timothy Zahn that I originally read as a teen that I liked called
A Coming of Age.
Out of print for a quarter century, likely to never see another print run, who knows when there will ever be an official ebook, and I of course can't link to a (reasonably) well ebook formatted PDF I made from a txt file I found on-line.
Doesn't mean nobody can PM me though...
