Interesting math books?

Question

Books

Good afternoon, dear toasters!
There was free time and a strong desire to read something like that in mathematics, but not to fill holes in knowledge, but for my own pleasure, therefore I am requesting not strict textbooks, but simply interesting reading material with a mathematical bias.
How mathematical? It is desirable so that not a couple of mentions of mathematics or a superficial description of division in a column, but a very deep bias towards the queen of sciences.
In what language? Preferably English- or German-speaking, but I also have nothing against Russian or French.
PS links are optional. I'll find it myself :)
Danke schön, comrades!
