The best thing about Amazon when it comes to finding new books (or any other kind of media) is that it’s a one stop shop; it’ll give you recommendations based on what you’ve purchased recently, and you can purchase things straight from there.
TV Tropes is a dangerous little rabbit hole, but I’m going to link to it anyway. It’s a wiki specifically focused on storytelling tropes (and, like Amazon, not specific to literature). While it’s not intended to act as a way to find new material, the way it weaves pages about actual entertainment, to the tropes that can be found in them, back to more entertainment means that finding something that will interest you will be simple.
What Should I Read Next? is probably the simplest of these kinds of sites. It asks you to enter the title of a book or the name of an author you enjoy and it’ll print a massive list of similar titles for you to peruse. And wouldn’t you know, the Info/Buy button next to the titles links straight to its Amazon search results.

Whichbook allows you to search for books based more on thematic lines rather than similarities to other books. It lets you select four gradient scales (like happy to sad, funny to serious, or conventional to unusual) and choose what point on the scale you’re interested in. It’ll give you a number of suggestions based on your selections.
The Staff Recommends is a bare-bones site written primarily by John Warner that updates with his professional suggestions once a week. It doesn’t take your personal tastes into account, but runs on the premise that if you find something that may interest you, it’ll be good.
