Torn apart by a catastrophic event, two astronauts find themselves thrown into parallel dimensions. And, with the fate of two Earths now hanging in the balance, the pair must find a way to save both worlds and themselves.

Aboard the International Space Station, scientists Alex Devine and Zandra Ivanov were the perfect team. They were on the verge of discovering a break-through means of interstellar travel - until disaster struck.

Thrown into two very different alternate realities, the pair now find themselves lost and longing; struggling to recreate the results of their research, but for very different reasons. While Zandra is driven to save the population of a dying world, Alex finds himself forced by a maniacal leader to use his Quantum Triangle technology as a doomsday weapon.

But the space between their universes is smaller than they realized. Can they work together across the quantum divide to be reunited once again? Or will their efforts fail, causing the annihilation of both their worlds?
