I was made aware of Cameron Stewart's 'Sin Titulo' web comic in the recently announced Eisner award results (The Oscars of the Comic Book World).
The story is fantastic, with twists and turns in many unexpected directions. Each weekly episode we follow the story of Alex MacCay as he first stumbles upon a mysterious photograph and then is systematically dragged into a harrowing chain of events, nightmarish encounters and surreal occurrences.
Every, single-page plot development leaves you desperate for more, with masterfully handled cliff hangers and fascinating character driven advancments in the narrative. Check it out - the Eisner is well deserved: http://sintitulo.txcomics.com/
