Sisters of the Jungle explores the history of primatology, a rare scientific discipline led primarily by women, from pioneers like Jane Goodall and Dian Fossey to author Keriann McGoogan's own adventurous field studies.

Since the 1970s, the science of primatology has been dominated by women—a unique reversal, as men usually outnumber women in science, technology, engineering and math (STEM) fields.

Today, one of those women is primatologist Keriann McGoogan, who has traveled to the far corners of the earth in search of wild primates. In Sisters of the Jungle, McGoogan combines stories about her own studies of howler monkeys (the loudest living primate) and lemurs (the most endangered group of animals on the planet) with those of the women who paved the way: intrepid scientists like Jane Goodall, Dian Fossey, Biruté Galdikas, and Alison Jolly who broke boundaries, made astonishing discoveries and ultimately shaped the trajectory of an entire branch of science.
