Is never the question.
Read everything. Read often.
I've read some writing advice that says that once you choose which genre to write in, you should go and read every book you can in that same genre. This way, you know the tropes, you know what readers want, and you can deliver.
Personally, I don't agree. I tend to follow the writing advice of maybe 2-3 authors, and the one I listen to the most is Sir Terry Pratchett.
I mean, the man was knighted for his contributions to literature!
He said that once you find your genre, read everything else. This way, something may spark and you can bring new ideas to the genre. It ensures you won't write a cookie cutter book that sounds like everything else out there.
When in doubt, I listen to Sir Terry.
