Overview

Are your bookshelves at maximum capacity? Do you have stacks of books piled on your nightstand, a cart overflowing with unread titles, or a box (or three) of books waiting for their moment? It’s time to tackle the chaos with The Overflow TBR Challenge
Your mission: Read 25 books from anywhere your unread books have started to accumulate—whether it’s a towering stack, a crammed TBR cart, or that “just one more” pile that somehow keeps growing. No library books, no new purchases—just the books you already own and have been meaning to get to. 
Clear some space, conquer your backlist, and finally enjoy the books you were so excited to pick up in the first place! Will you make a dent in your bookish overflow? Join the challenge and find out!
