Greener Mountains is the coming of age story of JP Barton, an adopted boy raised on a throwback Vermont family resort by the eccentric matriarch. A convergence of events propels him on a bumpy ride of self-discovery in which he realizes what is really important to him is right there in his own backyard.
JP was brought up by 'M', the mercurial aging owner of Barton's Family Resort. Despite already being in her 60's when she finds JP, she opts to bring him up herself and the two develop a unique bond from the start. By the time JP reaches his late teens, he is nearly running the place for her and is a hit with the resort's guests. Barton's is its own little world tucked away in the Green Mountains of Vermont next to a magical lake. The working class families that vacation there return year after year, partly due to the beauty of the place and partly due to the distinctive feel that M and JP bring to the place.
When a young, free spirited New York artist, Alice Flynn, arrives late one summer, JP's life is turned upside down. Completely smitten, he immediately begins spinning a story about himself to impress her. JP never felt comfortable with himself and figures there's no way this beautiful, quirky, cosmopolitan girl would ever fall for a simple small town guy who's spent his entire life on a tiny parcel of land in the middle of nowhere. JP begins to concoct a whole other life for himself as an NYU student who just happens to summer up here in rural Vermont. The more the lies pile up, the harder it is for him to eventually come clean with Alice. JP would do anything for her, but in his efforts to do just that, his lies drive her away.
Meanwhile, M has fallen ill and her slick opportunistic grandson, Eric, returns from NYC and seizes the chance to move in on the place. He knows she is leaving the place to JP who has become like a son to her, so Eric proceeds to sabotage their relationship. Using Alice against JP, Eric manipulates him into a series of erratic behaviors that drive a wedge between JP and M.. Soon Eric has weaseled his way in with both Alice and M and JP has become persona non grata with both. The harder JP tries to prove Eric is the one that is the troublemaker, the worse he makes things for himself.
Along the way, JP discovers that Eric's intentions with the resort aren't quite as pure as he would have everyone believe. The moment M dies, Eric plans to renovate the place, destroying the distinctive Vermont family feel and replacing it with a generic resort catering to a wealthier clientele, thus pricing out all the blue collar guests who have been coming for decades. Essentially destroying what M has spent a lifetime building.
It's not until JP accepts who he is, that he realizes what's most important to him. As a result he is finally able to win Alice and in the process save the resort. Greener Mountains is a story of finding out where you belong in the world and discovering that who you are is often more than enough.
