Editorial Review
Praise
"The routine acceptance of experimentation on monkeys has produced places that, unknown to the public, inflict misery and death on countless intelligent beings. Lindsay Oliver's brave and powerful book blows the cover off one of these institutions, documenting both the cruelty and the conflicting emotions of those whose job it is to obey orders. At this moment when even the US National Institutes of Health is recognizing that most of this research is pointless, Marshmallows Are Their Favorite needs to be widely read."
Peter Singer
Author of Animal Liberation
"A thriller, an exposé, even a love story. But even more than that, it is an intensely personal and revealing journey of one woman willing to risk her own safety as she navigates two identities in an attempt to shine a light on the truth."
Ari Solomon & Mikko Alanne
Award-winning producers of The Animal People
"Unforgiving, empathetic, raw and real. An eye-opener. A broken system that is fundamentally cruel, crude, and irrelevant in these technological times."
Ingrid Newkirk
Founder and Principal, PETA, and author of numerous books, including Animalkind
"Lindsay Oliver's courageous work clearly and shockingly reveals that too often scientists neglect this basic responsibility to nature's sentient and vulnerable beings. This honest story must be told."
John Gluck, Ph.D.
Professor Emeritus, former animal researcher, and author of Voracious Science and Vulnerable Animals
"If you care about animals and their treatment in laboratories, you need to read this very important book."
Robert Ingersoll
Primatologist, featured in Project Nim, and co-author of Primatology, Ethics, and Trauma & Trauma in Sentient Beings
