This question definitely involves SPOILERS, so if you haven't read the book, you might want to stop reading NOW.
Final warning!
OK, for those who have read it, I just finished and thought, "Well, that's a nice sweet ending. Barry saved the world and is about to be reunited with Helena."
BUT then I thought more about the final sentence fragment: "And he says–"
And it dawned on me that that last scene occurred at approximately 9:30 p.m. on Nov. 5, 2018 — the exact time that all the previous major timeline resets occurred!
So did Barry ultimately fail to reset the original timeline, because Slade lied to him about him to do it? Or was this just the author toying with readers?
Because everything in the final chapter and epilogue, up to that point, had led us to believe that Barry had succeeded and ended the catastrophic loop.
Anyway, I'd be interested to hear what other fans of this book think.
