Questions & Answers about Die Autorin, deren Roman ich lese, schreibt sehr spannend.

What does deren mean here?

deren is the relative-word equivalent of whose.

In this sentence, it links the relative clause back to die Autorin and shows possession:

• die Autorin = the person being talked about
• deren Roman = that person’s novel

So deren does not mean her in the ordinary personal-pronoun sense. It is specifically the form used inside a relative clause to mean whose.

Why is it deren and not dessen?

Because deren refers back to die Autorin, which is feminine singular.

For possessive relative pronouns in German:

• dessen = whose for a masculine or neuter noun
• deren = whose for a feminine noun or a plural noun

So:

• der Autor, dessen Roman ... = the male author whose novel ...
• die Autorin, deren Roman ... = the female author whose novel ...

The form depends on the noun being referred back to, not on Roman.

Why is there no article before Roman?
