A book to help couples communication?

I’ve been with my partner for over two years. We are very different people and the main obstacle in our relationship is I really struggle to communicate my needs to him in a way which he would understand and not take personally.
It’s my first long term relationship despite being 27(F) I feel so clueless on what to do :/

We have agreed to try and read a book together that will help us communicate and better understand each other.
Does anyone have any suggestions, that is not too spiritual/woo woo (he’s not spiritual) and has activities within it to help us?
Thank you so much in advance ❤️
