When Maricarmen meets Rey el Cantante, beloved small-time Robin Hood and local musician on the rise, she begins to envision a life beyond the tight-knit community of el Caserío, Puerto Rico--beyond cleaning houses, beyond waiting tables, beyond the constant tug of war between the street hustlers and los camarones. But breaking free proves more difficult than she imagined, and she soon finds herself struggling to make a home for Rey, his young brother Tito, and eventually for their daughter Nena. Until one fateful day changes everything. Fifteen years later, Maricarmen and Nena find themselves in the middle of a murder investigation as the community that once rallied to support Rey turns against them. Now Nena, a teenager haunted by loss and betrayal and exploring her sexual identity, must learn to fight for herself and her family in a world that is not always welcoming. For lovers of Elana Ferrante's Neapolitan novels, This Is the Only Kingdom is an immersive and moving portrait of a family--and a community--torn apart by generational grief, and a powerful love letter to mothers, daughters, and the barrios that make them.
