For Machine Learning theory related to Data Science I'd highly recommend "The Hundred-Page Machine Learning Book" by Andriy Burkov [1].
According to the author, by reading one hundred pages of the book (plus some extra bonus pages), you will be ready to build complex AI systems, pass an interview or start your own business.
It is a read first book and buy later if you think it is good enough.
