Sweet. Wistful. Dreamy.

Aaron and Rachel are a young couple who are deeply in love and engaged to be married. But the morning after Aaron proposes, he wakes up alone. It’s not that Rachel has left him. It’s that she doesn’t exist — at least not in Aaron’s world.

Aaron eventually learns that he somehow has crossed into an alternate dimension where he and Rachel are no longer together. Each day, in fact, brings a new reality and a changed set of circumstances. Untethered from the life he knows, he’s left bobbing adrift in an endless sea of parallel universes.

With nothing but true love to keep him afloat, Aaron somehow must find a way to return to his own reality — and to his beloved soulmate — or else risk losing himself across the massive, wide-sweeping reaches of the multiverse.
