It gives me a lot of Riverdale vibes and reminds me of a story I read on Wattpad long ago. Confessions About Colton. Which I really loved. Adding some more details to your blurb would help a lot, as things are quite vague this way. I'd also suggest a better opening line for the blurb to catch the reader's attention; something that really hooks them in. This is just a suggestion, but maybe start off with the killer or Marcello's brutal murder?
There's a serial killer in Wood Maple and Joseph Ronchetto plans to catch him.
The teenager's life is turned upside down when his childhood friend is found brutally murdered in his own home. Consumed with grief and anger, he sets out to find the culprit. (Something to add a little more emotion behind his friend's murder would help a lot here) I'll leave the rest to you, as it's your story and you can always tweak my suggestions if you'd like.
