Storygraph has revamped its recommendations so why not make a challenge that focuses on that!

To find your recommendations go to your Home page, and then scroll down to just below your To-Read Pile, you'll see your Recommendations. Click the Explore button. These instructions are the same on both the desktop site and the Android app, the iOS app may be different, I'm not sure. Alternatively, you can click here.

All of the books read for this challenge should be found via the Recommendations section.
