Two of my three favorite monthly comics are Image books, actually: the phenomenal fantasy/sci-fi/family drama/comedy/ghost story/etc. Saga, written by Y: The Last Man's Brian K. Vaughan and illustrated by Fiona Staples, and the weird, grim sci-fi epic Prophet, written by Brandon Graham and illustrated by a slew of fantastic indie artists, including Simon Roy and Portland's Farel Dalrymple. Hey, you should read them! For free!
Over the weekend, Image put a bunch of their 2012 #1 issues on Comixology for free—they'll stay up there, and they'll stay free, permanently. I can't recommend Saga enough, and Prophet's great, but also worth checking out are the noir horror Fatale, by Ed Brubaker and Sean Phillips, two books by Portland writer Joe Keatinge, Glory (illustrated by Ross Campbell) and the Portland-set Hell Yeah (illustrated by Andre Szymanowicz), and a couple of Hickman books, Secret and The Manhattan Projects. Go, download 'em to your phone or iPad, read 'em online, whatever—the first issues of each of those books I just mentioned are all free, along with a bunch of others. If you're one of the people who (usually correctly) argue that comics aren't worth four bucks an issue, and are too hard to find, and are too hard to get into, well... here. Image is making it easy for you. I wish more publishers would follow their lead.
