If I were to pay you 10 billion dollars to suggest a book I’m guaranteed to love, what book would you suggest?

I often take suggestions of people's favorite books but haven't read anything that I loved or couldn't put down lately.

If I were to pay you 10 billion dollars, what book would be your safest suggestion that any person would absolutely love?

Any writer, any genre, any length.

Thank you in advanced for your suggestions!
