Read the 30 books from the Diverse Spines x Ideal Bookshelf Mug (mug link | bookshop.org link).  This challenge is different from others in that the titles are set but there is a bonus prompt to read any book from any of the authors on this list!  (This isn't endorsed by Diverse Spines or the Ideal Bookshelf...I just wanted to read all the books on the mug and made a challenge and thought others in this community might enjoy it too.)
