Nesta has finally turned away from the path of self-destruction (not that her sisters know). She then realizes she's pregnant with Cassian's baby... It focuses on Nesta's journey through pregnancy and her relationship with Cassian, her baby and her sisters. (I can't write summaries sry) T cuz I'm paranoid (Post-ACOWAR & ACOFAS but Nesta doesn't go to the Illyrian mountains)
Maybe Nesta is too much for this world. Maybe this world is too much for Nesta. TW: depression
