What are some alternatives to "that they wrote"?

Is it correct to say "the book that they wrote" or "the book which they wrote"?
Both are grammatically correct, but "that" is generally preferred in restrictive clauses (clauses that are essential to the meaning of the sentence), while "which" is often used in non-restrictive clauses (clauses that add extra information but are not essential).
