Book recommendations for novice looking to learn

Hello, I was raised Christian but never really connected with it and I always just practiced prayer and worship in my own way. My partner studied religion in college and we often talk about our beliefs and he tells me a lot of things I say align with Islam. I have always felt strangely pulled toward the religion even though I know nothing about it and have felt shame for not making the effort to learn. My finances are limited so I am wondering if there are any books on kindle or libby that anyone can recommend. It would be much appreciated.
