Silent City Series by Élisabeth Vonarburg

Only a handful of humans remains in the City, the final stronghold of science and technology in a war-ravaged world. Forged from genetic materials stolen from the Outsiders, Elisa is the first of a new race--endowed with the remarkable power of rejuvenation. A metamorphic journey into (the) disturbing possibilities of gender, social order, and genetic science.--William Gibson.

A future society, where women far outnumber men, has abandoned the models of patriarchy and matriarchy and established new gender roles. But Lisbei, a young thinker whose gift is exploring the past, confronts the new establishment in order to force changes of her own. The Maerlande Chronicles is a sequel to the critically-acclaimed novel The Silent City.
