i've never read a dungeons and dragons official novel in my life, but picked up the Timeless trilogy by RA Salvatore because they were available as audiobooks on my library app.
beyond just being really good books with a central theme being about the longevity of some fantasy races and their resistance to change in a world constantly in flux, i came out of the series utterly enraptured by the relationship of Zaknafein (Drizzt's dad) and Jarlaxle. obsessed with these old men.
