There are a lot of big success stories in DC's Rebirth initiative so far, but one of the biggest and most surprising has been The Flash.

The series, from writer Joshua Williamson and artist Carmine Di Giandomenico, has tied very closely to DC Universe: Rebirth #1, dealing with the return of the pre-Flashpoint Wally West as well as touching on the mystery of The Comedian's blood-splattered button from Watchmen appearing in the Batcave.

As a result, the book has sold out everywhere and retailers I've talked to have said it's the most sought-after Rebirth title among fans who got on board late.

For those who are all caught up, though? DC has provided ComicBook.com with an exclusive preview of The Flash #2, due in stores and on digital services like ComiXology on Wednesday, July 13.

“2016 is the 60th anniversary of Barry Allen becoming The Flash, and it’s a privilege to be a part of it,” said writer Joshua Williamson. “‘The Return of Barry Allen’ in The Flash #79 [1993] is one of my favorite comics of all time. It’s where I became a Flash fan for life.”

“LIGHTNING STRIKES TWICE” Chapter Two: In issue #2, The Flash trains novice speedster August Heart to help protect the people of Central City from the Black Hole, a new breed of rogue with a deadly agenda for the Fastest Men Alive.

There are a lot of speedsters around, and more to come as Godspeed has yet to make his play. What will it all mean for Barry? And what could Barry and Wally mean for the multiversal implications of DC Universe: Rebirth and the Watchmen connection? You'll have to check out The Flash #2, from Williamson, Di Giandomenico, and FCO Plascencia on colors.
