Rigil Kentarus

Publisher's blurb: Terra’s closest if not first colony, the binary planets of Rigil Kentarus and Riken Minor are just 4.3 light-years from Terra. Rigil Kentarus was settled by a mélange of Terran Alliance member-nations, some of which still leave their mark on the world (“Little America”), while others were wiped out by the Succession Wars, Jihad, and reconstruction. The twin worlds only recovered in the Republic of the Sphere, but generations-old refugee camps nurse hatred for the current government.
