Reddit reviews The Flash (2011-2016) Vol. 1: Move Forward

If you really like The Flash and want to read some of his comics, I would suggest checking out the Mark Waid (writer) run that began in 1990 and ran for several years. It's widely considered to be essential Flash reading. given that it's from the 90s, the art is very much in the 90s style, which a new reader might find off-putting. It's also a run where Wally West is the Flash, not Barry Allen.

If you want good Barry Allen stories with a more modern art style, the "New 52" run that started in 2011 is pretty solid, and continues to be all the way up through the current ongoing run. This took place right after "Flashpoint" (which you can read first or not, it isn't essential), which involved Barry messing up the timeline (something I'm sure you're familiar with from the show). The Justice League book from the same era is also decent, and the Batman run (if you're interested) from that era is SUPERB.

Here's a link to the new 52 Flash on Amazon, which you can buy digital from ComiXology (best if you have a tablet), or trade paperback (a collection of several of the monthly issues).

Also here's a link to the first volume of Mark Waid's run

Note: You can usually buy these trades at bookstores like Barnes and Noble or your local comic book shop. If you care to, I'd recommend buying from a comic shop as much as possible because they need the support.

Personally for newcomers to the comics I recommend the Flash New 52 it's a fresh start to the Flash mitology and you get to know almost all the cast of the show (keep in mind that certain characters from the show don't exist in the comics I.E: Harrison Wells and some characters are completly different like Joe West), the art is magnificent just as the writing. Here's a link to a digital version of the first volume of the comic (issues 1-6) and it's only 9 dollars.

heheh I'd go with what u/Paunchvilla said, much more specific. Here's a link to volume 1 though, which should start you in a non-confusing place.
