Please give me something magical

When we read a type of book we have never read before it gives us an unique lush experience. When I read my 1st couple of fantasy books I felt like this , similar with several Sci fi . I felt the same when I read few eastern fantasies and we novels.When I read dungeon crawler , i really liked it because It was my 1st litrpg.

So help me decide a series ( not a standalone that ends quickly) that can provide an unique experience . A series When u start u can read night after night without thinking of ever stopping .

Thanks .
