Opening the Span

They have finally found the road home. Opening it may lead the enemy straight to humanity.After years trapped inside a dying region of space, the Endurance reaches the last refuge of the Orun—the silent people she once helped hunt.

They have counted every death. They offer no forgiveness. But they know of a road leading out of the far pocket and back to a living sky.

At the end of that road stands the Span.

The crossing is sealed, the ship is failing, and Maric Tann has found their trail. If the Endurance opens the way home, she may show him exactly where humanity lives. If she leaves it closed, her crew will die in the dark—and Earth will never receive the warning they have crossed five years to deliver.

Captain Julian Mercer must hold a broken crew together through one final campaign, make peace with the people they wronged, and decide what a captain is allowed to spend for home.

But the last crossing will cost the Endurance everything she has left.

And even victory may only buy humanity time.

Opening the Span is the third and final book of Spent Light—a hard-science-fiction command adventure about first contact, damaged ships, impossible choices, and a crew fighting its way home through a dying universe.
