In a world where humanity is at the edge of extinction, Eleanor Cross has to figure out the balance between defending herself and her Plumbers from ONI and working with the UNSC to take down the Covenant.

There are an infinite number of universes out there, which are infinitely different from each other in some ways, but oddly similar in others. This story takes place in a universe where Ben Tennyson and his team were born in the 2500s, a few years before the Covenant attacked humanity.
Decades later, the Anodite-Human hybrid Eleanor Cross must return to the organization that betrayed her and her family to stop the Covenant from blowing up the entire galaxy in a misguided attempt to attain divinity. And as luck would have it, she is partnered with the only person in the UNSC who stands a chance against her — the Master Chief.
