Beasts is a book about time—time passing, time cycling, time fossilizing, time writing itself on the human imagination. Such a scope might crumble in a lesser poet’s hands, but Sagan’s touch is dependably deft and fresh. Here are poems woven of high and low, shadow and light, visible and invisible, human and other-than. Tuned to the resonant universe, they touch us deeply. —Anne Valley-Fox, author of Nightfall
