So I would totally suggest a few of my favorites here:
A Discovery of Witches (Trilogy) - Phenomenal, features time travel, witches, vampires, and a well developed world.
Russian Winter - A look at a soviet ballerina that I just can not do justice too. I am still reeling from this book and it's been my favorite in the years since I read it.
And because I'm reading it now and the final book is about to drop - A City of Brass. Late 1800s, middle eastern, and features magic and genies.

Category to Suggest - Historical Fiction
And to put in that category, anything by Michelle Moran she is a fantastic historical fiction writing and really draws people in to her stories.

Another Category - Biographies
Best one I've read recently is Georgiana: Duchess of Devonshire. While 100 years before Charming's setting the Ton of British Society is fascinating and she was an amazing woman. Fun fact the movie The Duchess is based on this book.

I'm not doing justice to any of these books, but I will talk passionately about any of them to you because they are all my favorites and I feel everyone should read them. So far everyone I've recommended them to has loved them and has difficulty putting them down.
