Novel for those who find wonder in mathematics

I truly enjoy novels that are both educating as they are entertaining. It needs to be remembered that "Uncle Petros and Goldbach's Conjecture" and its main character, gifted Greek mathematician Petros Papachristos aka uncle Petros, is a fictional character many other characters appearing in the book and working on their theories are very much facts from history of mathematics field, and it makes the book even more gripping in its story.
