Voices is Ursula LeGuin’s sequel to Gifts. It’s an excellent sequel, set many years later. She does a great job of building a convincing occupied city, filled with resentments and unease. The characters all ring true; Memer and Galamand and the oracle house are detailed additions to the world, as is the whole city of Ansul. Gry and Orrec have matured and changed since the last book, but remain at their core the same people.
If you liked Gifts, read Voices.
