“[Mathematics is] only real when shared” ― Jon Krakauer, Into the Wild

My new favorite book:

Theories, Sites, Toposes; by Olivia Caramello

It is unbelievably readable for modern graduate students or those familiar with basic Category Theory. This is in contrast to the difficulty one has when they start up Johnstone's books. Olivia Caramello is a super hero of mathematics.
