Read as many fantasy and sc-fi classics throughout 2025 as you can. The goal is 24, but don't take it too seriously. This is just for fun, after all. As to what constitutes a "classic," there are three general guidelines:
1. The book has been widely read and loved by at least two generations.
2. The book has influenced other authors in the genres of fantasy and sci-fi.
3. The book is critically acclaimed.
Obviously, these rules are not set in stone. Just don't choose anything that's completely bonkers.
