Mr. Universe — Arthur Slade

Seventeen-year-old Michael goes to visit his eccentric mad-scientist uncle while he's busy working on yet another time-travel experiment.

In the cluttered lab, Michael's uncle barely notices him. And he keeps muttering things like “quantum multiverse transporter," so Michael has to entertain himself. Which is how Michael accidentally ends up in an alternate universe. Everything looks remarkably similar to his own world but with a few key differences, like lizard men dressed in gray suits and three-wheeled vehicles. And then there's Emily, a sassy, confident girl who needs Michael's help before he can find his way back to his own dimension.
