Where do I find books in my genre?

One of the biggest pieces of writing advice is “read in your genre”, but with so many books coming out all the time, and Amazon only showing me a fraction based on previous searches, how do I discern which ones to read?

I am specifically writing in the YA Fantasy / Christian genre, and am just not sure how to find recently published books that would be worth my time. I know there are great ones, I’m just not sure which ones those are!

Any advice, even from writers of other genres, would be highly appreciated!
