Books like 7 Husbands of Evelyn Hugo

Hi, so this book recommendation is for my girlfriend, she enjoyed this book very much and told me that she would love more of such books . More about her taste:

1. She is not a fan of Colleen Hoover.
2. She is not into Classics.
3. She likes Isabel Allende, and has read all of her books.
4. She likes John Green, and has read all of his books as well.

Any suggestion would be very helpful, thanks a lot in advanced!
