Reddit reviews Primates: The Fearless Science of Jane Goodall, Dian Fossey, and Biruté Galdikas

Try anything by Mary Roach. Her nonfiction books cover a variety of science topics and are interspersed with her stories about traveling to the studied locations and misadventures with equipment like space toilets.

If you want to combine nonfiction, travel, and graphic novels, I'd heartily recommend Primates, which just came out. It's about Dian Fossey, Jane Goodall, and Birute Galdikas (who is always forgotten), arguably the most influential great ape researchers of all time.
