In the lower bowels of teenage hierarchy, Richard crawls through the shadows of high school. As he navigates the world of hungry egos and runaway hormones, shit hits the fan when his drug-addicted mother gets thrown in jail. Now he must figure out how to pay rent, escape social services and keep his sanity intact. Amid his daydreams of revenge and guilty fantasies, a sudden surge on the popularity shows him a different side of life. Will it all work out in the end? A little cynicism can be healthy, but too much and things get toxic.
Hierarchies are usually described by levels or reaches, by whether you are at the bottom, the middle or the top. So he was at the bottom? And "bowels" doesn't work well for another reason - combined with "shit hits the fan" makes for unappealing imagery. I also think "crawls" might be the wrong word. It makes him sound feeble, unenergetic. Egos are usually described by their size. So, instead of "hungry egos", maybe - oversized egos. I wonder - wouldn't social services pay his rent? Revenge on who? "A sudden surge on the popularity" - did you mean a sudden surge in his popularity? The use of the word "different" is imprecise. Choose a more specific word. Will what work out in the end? Again, be as specific as you can.
I'm no expert on blurbs, but the ones I recall reading are all a bit longer than this, and I think it could stand fleshing out a bit. I've done so interlined comments on what you did write: In the lower bowels [are there upper bowels?]of teenage hierarchy, Richard crawls through the shadows of high school. As he navigates the world of hungry egos and runaway hormones, shit hits the fan when his drug-addicted mother gets thrown in jail. Now he must figure out how to pay rent, escape social services, and keep his sanity intact. Amid his daydreams of revenge and guilty fantasies, a sudden surge on the in popularity shows him a different another side of life. Will it all work out in the end? A little cynicism can be healthy, but too much and things get toxic. [something seems to be missing here -- how did we suddenly get to cynicism?]
I like the title. I could see myself picking up that book based on the title alone. But the blurb gives me two separate impressions. For the first part, I feel like this is going to be something heavy about how bad Richard will have it. Perhaps it might even be a social commentary on the treatment of people. Then, for the second half, I get the impression I'll be getting some sort of YA high school action, and it'll be more lighthearted than the first half suggests. Now, as evidenced by several posts in this very topic, I'm not great at blurbs, so take what I say with a grain of salt. Also a glass of water. Salt will dry you out quickly. Take the overall tone of your book and let it reflect in the blurb.
