Does 'The billionaire's accidental bride' has a novel/book?

Hey everyone!

I've got 2 questions about 'The billionaire's accidental bride' - on Pocket FM:

1. Does it have a book/ novel to read from? instead of listening to it...

2. I've read, it was written by 2 persons. The first was the original author, and then came someone else and 'added more to the story- Does anyone knows up to what chapter was the original author story?

Thanks!!
