One man will destroy the past to save the present.

The price is too high.

But it may already be too late to stop him.

Life settles into a routine for the inhabitants of Chiron Colony, humanity’s first interstellar settlement, after the threat of the time traveler Gifford has apparently been eliminated.  But the Hourglass and its leader, Admiral O’Dare, are not content to rest on their laurels, convinced that time travel remains a palpable threat to human civilization.  When Annette Sutton uncover a possible secret plot to eliminate the principal members of the Interscission Project decades in the past, when they had only just met, the colonists' idyllic peace is shattered.

Can Martin and his people head off disaster as the Admiral moves to destroy the potential for time travel, once and for all?  Or is there a deeper agenda in play?  As loyalty and duty become pawns in the race to prevent the erasure of all that they have accomplished, Martin will have to decide once and for all how far he will go to save everything and everyone he loves.
