For those who aren’t aware, if you have Amazon prime you can borrow up to ten books at a time on the kindle app for free 
I’ll start with some good ones I’ve read lately:
Unspeakable things
The Good Samaritan
The other wife
Queen bee
Other non prime ones I liked (paid for but not expensive):
The beekeeper of Aleppo
The tattooist of auschwitz
The silent patient
