Here's one I've been wanting to read. I've seen it on several lists.

As noted, I couldn't cover everything, but if you glance elsewhere on many of these sites, you'll find more of the best. In the sidebars of the Goodreads Choice pages, above for example, other "best of" genres are covered. Kirkus and others also cover multiple genres. (And yes, I did leave Romance off the list. It's just a bit too close to home, but there are online lists that cover the various sub-genres of romance novels.
I hope you found something you'll enjoy.
