The first Flash Annual of the post-Rebirth era plants the seeds for Flash War, first by peeking into Wally West's life since his return and by exploring the tension between him and Barry.

The Flash #38 is all about second chances, and it succeeds in showing that with Barry Allen and August Heart's story while still having fun with the Rogues.
The Flash #37 intertwines Barry's work life with his superhero life, creating a mystery he must solve as both CSI Allen and the Flash.
The Flash #36 reintroduces the Rogues as a mysterious murder takes place in Iron Heights. But how can Barry solve it with so much against him?
The Flash #35 reveals Meena's motivations for her heel-face-turn, and reintroduces the idea of a Barry and Wally team-up.
The Flash #33 makes the most of its Metal tie-in, bringing as much action and fear to The Flash as possible without losing Barry's human touch.
The Flash #32 re-introduces us to Iron Heights and sets the scene for Barry Allen's future dealings there while igniting plot points that will go off later.
The Flash #31 concludes Bloodwork and sets up the next arc of the series, which takes place at Iron Heights. It also happily brings the Wests back in.
