- "The Neverending Story" by Michael Ende as a kid
- "The Lord of the Rings" by J.R.R. Tolkien as a teen
- "The Realm of the Elderlings" by Robin Hobb
- "The Ea Cycle" by David Zindell
- "The Manifold Trilogy" by Stephen Baxter
These books' worlds absorbed me so completely in the most positive way!
Though I must admit I'm a fan of rereading anyway. Don't know how many unknown books I skipped for a reread of know ones. ¯_(ツ)_/¯
