In this forward-thinking and eye-opening book, feminist bisexual and genderqueer activist Shiri Eisner takes readers on a journey through the many aspects of the meanings and politics of bisexuality, specifically highlighting how bisexuality can open up new and exciting ways of challenging social convention.Informed by feminist, transgender, and queer theory, as well as politics and activism, Bi is a radical manifesto for a group that has been too frequently silenced, erased, and denied—and a starting point from which to launch a bisexual revolution.
