Any recommendations on books covering UX and UCD?

Hello everyone!

My friend and I are writing a bachelors thesis this year and we are developing an application along with it. The main focus of the thesis is to utilize user experiences (UX) and user centered design (UCD) and document the whole design process. We will also cover the technical and developmental side, along with software development methodologies, but that is too early right now.

With that being said, what are good books that cover UX and UCD?

Thanks!
