Andrews and her daughter have worked together on 23 books since they first started working together in children's publishing. She admitted that it was a pleasant surprise to discover that their working relationship made their personal bond stronger.
"We now face each other as two equal women and we're really very compatible," the Daily Express quoted Andrews as saying.
"We didn't think we would be at first because we're kind of two bossy ladies and we thought that we might clash, but we actually don't," she added.
The duo most recently released ''The Very Fairy Princess''.
