How far would you go to find your true home?

Lucy—single, childless, in her thirties—studies insects and ecosystems, in part to make sense of human behavior. That hard-won insight is shattered when her mother dies prematurely, her sister claims the California family home, and Lucy learns that her biological father is apparently a Costa Rican they knew when the family spent summers in the coastal village of Palmita.

Reeling, Lucy heads south in search of this phantom father. But he is nowhere to be found, and none of the locals seem to remember her. The dreamy, off-grid paradise she recalls from childhood has become a hard-edged town leery of outsiders. Is Lucy an interloper, too? Or can she find a way to belong—rethink her place in the world and expand her notion of kinship and home?
