This is a growing pains type of book, something that makes you look at being a young adult stuggling with growing up in a different way, maybe in a wring you out kind of way. Possibly the only other books that made me feel this way would be the series by Megan McCafferty.
Sherwood Smith, author of Inda and Crown and Court Duel has recommended it on livejournal (http://community.livejournal.com/athanarel/111008.html) and describes it very well - "Greensleeves had what I considered the very best illustration of the difference between love and mere (or not so mere) attraction that I have EVER seen. And that included very wide reading in adult books at that time. In fact, much of the popular adult literature I read in the sixties mixed the two--usually mistaking attraction-at-first-sight for actual love, which usually ends in tragedy in real life. The thing about Greensleeves is that it is a delightful story, not the least bit preachy, and not a single inappropriate word or action, though it deals so directly with potentially strong material. I thought Jarvis a genius. And more clearsighted than many so-called adult writers.
The story, briefly, is about a girl named Shannon whose divorced parents are both famous. So she's spent time partly in Europe, partly in a small town in USA. She feels like she doesn't fit anywhere. When it comes time for college, she panics. So her 'uncle' hires her to go in disguise to this tiny college town to investigate a very peculiar will. There is no danger involved, just a very odd set of circumstances around this will, and he wants to know if the recently deceased elderly lady was sane, or coerced, or what.
So Shannon makes up this ridiculous persona, and goes off to investigate, getting a job as a waitress. Among the distinctive characters she meets are two guys . . . well, I'll stop there. "
