RASL: The Drift by Jeff Smith
RASL: The Drift deals with alternate universes. Worlds that are just like this one, with only the slightest differences. Looking for those small clues is sometimes helpful, sometimes upsetting, and this is especially true if you are not entirely sure what dimension you are in.
A copy of Blonde on Blonde credited to Robert Zimmerman instead of Bob Dylan is RASL's first clue that he should not be where he is. Yet it is already much too late.
RASL is our anti-hero. He pioneered drift technology with his associates Miles and Maya, using Nikolai Tesla's research. RASL and Maya are also doing their own, more private research without Miles' knowledge. Instead of letting this amazing machine fall into the hands of the government, he uses it to skip this plane of existence and become an interdimensional art thief.
He steals works that Picasso did not paint here but did in other timelines. RASL then sells them for a profit in his reality. It is a lucrative job, though one with no long-term security. But what is future worth to a person who can travel through space and time?
RASL soon discovers that he is not the only individual drifting between worlds. There's this lizard-faced thug in a trenchcoat. While Rasl's hunting art, this guy is hunting RASL.
Jeff Smith is an established figure in the world of comics. His Bone series for children is a gorgeous blend of Disney and Tolkien. For this, his first adult series, he has combined film noir with Bradbury, The results are most impressive.
RASL desperately needs help, but he doesn't know whom he can turn to or trust. His girlfriend in the real world is murdered, so he escapes to another world to see if she can help him there. Still, wherever he goes, the lizard-faced man follows.
