Depends. How serious is this parody supposed to be? I know that they don't always have to be comedic, but at a base level this sounds a bit on the dark side. (I notice that you have "humorous" in the description, but I figured I'd ask.)
Also, it seems a bit wordy in places — like you could stand to trim it down. If it were up to me, I'd probably make it look like this:
"Love — shunned by the cynical and desired by the covetous. A force that cripples, yet transforms in kind. A humorous tale of jealousy, heroics, and a princess' 'escort.'"
That's just one possibility, of course. It depends on the content of your parody. And on that note, I have to ask: is this all the information you want to reveal in this line? As in, when I think of summaries, I think of a brief description of some of the events that'll happen. Like "A knight armed with a magic sword embarks on a quest to slay a dragon." Here you've got some of the themes at play, but not much in terms of actual happenings...not that that's a bad thing, but it's just something I thought I'd bring up.
Hope that helps you out. Good luck to you.
My Wattpad — A haven for delightful degeneracyWell, it has small bits of Scott Pilgrim and Super Mario, but most of it is original. I'm calling it a parody because it's not your typical romance story, hence the first chapter.
"The power of love is shunned by the jaded and bitter and desired by the envious. A potent force that cripples the powerful, it transforms the weak into heroes. A humorous tale of jealousy, heroics, and a princess "escorted" from one castle to another."
