is a Latinx retelling of the Brothers Grimm’s and reevaluating border, identity, and immigration narratives through the unlikely amalgamation of physics and fairy tale. In this full-length poetry collection, the girls of embark on a quest to discover what is real and what is possible in the realms of imagination, spurred on by scientific curiosity and emotional resilience. Following a structural narrative arc inspired by the archetypal hero’s journey, sisters Rosa and Nieve descend into the desert borderlands of New Mexico to find resolution and healing through a bold and fearless examination of the past, meeting ghostly helpers and hinderers along the way. These metaphorical spirits take the shape of circus performers, scientists, and Lieserl, the lost daughter Albert Einstein gave away. Poet Jennifer Givhan reimagines the life of Lieserl, weaving her search for her scientist father with Rosa and Nieve’s own search for theirs. Using details both from Einstein’s known life and from quantum physics, Givhan imagines Lieserl in a circus-like landscape of childhood trauma and survival, guided by Rosa and Nieve.
