Eternal Flame (The Flash - Book 3)
16 parts Ongoing Three years ago, Zoe Sparks was affected by the dark matter wave released by the particle accelerator explosion and became the Phoenix. Fighting alongside her boyfriend, Barry Allen/The Flash and their team at S.T.A.R. Labs, she protects the city from metahuman threats.
After defeating Zoom and Hellfire, losing Henry Allen and Amber Hale, meeting the Flash from Earth-3, and saying goodbye to Jesse and Harry Wells, Team Phlash must face a new threat, Savitar, the God of Speed.
Zoe also learns that Barry created an alternate timeline called Flashpoint, where he saved his mother from being killed by the Reverse-Flash and as a result, also saved her parents from dying in the fire her future self accidentally caused. Realizing how dangerous the ramifications of his decision was, Barry reset the timeline and returned to find that not only had he changed his own life, but also Zoe's and their friends.
