Merta is lonely. One of the last pixies in Ireland, she's seen her own kind diminish, and now her adopted human family is migrating to America. But Merta isn't about to let her favorite people leave without her. The new, strange land she encounters is sparsely populated with humans but abounds in Native American spirits. Merta is herself adopted by one native entity, Bear. Together they encounter great danger and wonder as two cultures clash and finally intertwine.
