One great approach is to create a little book club just for the two of you. Pick a variety of books from different genres and read them together. Then, during your discussions, you'll be able to gauge which ones she really enjoys. Also, look at any subscriptions she might have, like to a magazine or a streaming service. The content there can give you an idea of the kinds of stories she's drawn to.
You could start by asking her directly about her favorite genres. It's the simplest and most straightforward way.

If you find such a situation, it's a very serious matter. You should quickly check if she is breathing. If not, you might need to start CPR if you are trained to do so. At the same time, call an ambulance. And when help arrives, stay calm and provide any necessary information about her health history.
It's not a suitable or common topic to discuss. Moms deserve respect and positive portrayals, not something like this that might be seen as odd or inappropriate.
