Saga by Brian K. Vaughn and Fiona Staples
Who needs new Star Wars when you have Saga, a fresh science fiction/fantasy epic featuring star-crossed lovers, bounty hunters, and a fabled forest of spaceships. Seemingly every page features a brilliant new character design, and a thrilling turn of fortune, and a stirring display of true love, and a laugh. Think The Princess Bride with spaceships (and nudity). The first issue is a free download, so you have no excuse not to try it.
The first volume is $9.99 at Amazon. You can see more of the best of 2012 here.
