The complete series in the publicized order. Some might like to read the last book «New Spring» first because it takes place before book 1, but to me that makes no sense and can potentially be spoiler’ish.

The main story about Geralt and Ciri, excluding all other books. See my The Witcher Universe list if you're interested in more of the books, or before you decide if to skip everything and read only the saga.
