Dark Passage

What do you give up to sign this?

"She had the equation. She didn't have the last symbol. She started building anyway." A lone physicist's breakthrough in faster-than-light mathematics sets a ship under construction — and a corporate saboteur is the first to realize what's actually being built is worth more than its backers know. Before the ship is even finished, the reason for building it changes completely: a fleet arrives from the direction of Proxima Centauri, in a mode that fits no existing category. Not an invasion. Not a rescue. Something else.

Dark Passage is less interested in the spectacle of first contact than in what comes directly after it — the founding compact between two civilizations who have no precedent for each other, built not on trust but on costs both sides are willing to name out loud. The question the book keeps returning to is the one on the signature line: what, exactly, are you agreeing to give up?

The opening movement of a trilogy and its companion, Vel, Dark Passage is science fiction at the scale of deep time — spare, patient, and unwilling to hand you the easy version of what "first contact" means.
