Harry Potter and his twin sister Everlily begin their third year at Hogwarts, while a supposed mass murderer has broken out of prison in order to kill them...or at least that's what everyone thinks. Sequal to the Potter Twins and the Chamber of Secrets.

Continuing from The Potter twins and the Philosophers Stone Harry and Everlily return to Hogwarts for their second year, and must unravel the mystery behind Slytherins legacy.

Harry Potter has a twin sister, Everlily who also lived that night and remembers their past. Together they go through Hogwarts and face Voldermort. Sorry for the bad summery.
