Craig Santos Perez is the author of four books of poetry, coeditor of three anthologies of Pacific literature, and cofounder of Ala Press. He is an indigenous Chamorro from the Pacific Island of Guam and, in 2010, was recognized in a resolution by the Guam Legislature as "an accomplished poet who has been a phenomenal ambassador for our island, eloquently conveying through his words, the beauty and love that is the Chamorro culture." He lives in Aiea, Hawai'i.

"Native Pacific Islander writer Craig Santos Perez has crafted a timely collection of eco-poetry comprised of free verse, prose, haiku, sonnets, satire, and a form he calls "recycling." Habitat Threshold begins with the birth and growth of the author's daughter and captures her childlike awe at the wondrous planet. As the book progresses, however, Perez confronts the impacts of environmental injustice, global capitalism, toxic waste, animal extinctions, water struggles, human violence, mass migration, and climate change. Throughout, Perez mourns lost habitats and species and faces his fears about the world his daughter will inherit. Yet this work does not end at the threshold of elegy; instead, the poet envisions a sustainable future in which our ethics are shaped by the indigenous belief that the earth is sacred and all beings are interconnected--a future in which we cultivate love and "carry each other towards the horizon of care.""
