A Debt of Stars

Stars are dying ahead of schedule—not collapsing, not exploding, but simply going dark, as if someone flipped a switch. Romy Halden, a temporal nomad who has surfed relativistic transit for six hundred thousand subjective years, discovers the extinctions are spreading from a single point in the galactic halo. Together with her navigator Juno Tessaro and the oldest living Driftborn, she races across deep time toward a truth that could erase them from existence—or give the universe one last chance to endure.
