Meanwhile (2010)

Jason Shiga's pick-a-path comic puts the timeline in your hands. You follow thin tubes and tabs from panel to panel, forwards, backwards and upside down, choosing as you go among 3,856 story possibilities that take in time machines, doomsday devices and quantum physics. For a paradox lover this is the purest test on the list, because you can actually go back, try again and watch a choice ripple out, then work out how the branches fit together. Mapping it becomes a puzzle in its own right. It suits readers who enjoy logic games and branching plots more than a single emotional arc.
