Parallel Lines

A gay romantic sci-fi comedy

Change your choices.
Change yourself.


A stolen technology gives Thomas Arnold a chance to explore how his life would have turned out if he’d made different choices.

But with the creator of the tech chasing him down — and each jump poking holes in the fabric of space and time — can Thomas find his own best life before the universe (like his failing marriage) comes crashing down around him?
