Dual Core. Core Control 1, #3

Peace. Peace never lasts. Wynne's hard-won victories bought him some breathing room, but when a Tyr, neighboring core, calls its allies he knows that he'll be uncovered and destroyed unless he can find some way to evade Tyr's notice. Working with his adopted tribe of survivors and a few more uneasy allies, Wynne hatches a desperate plan to capture another core. But as he finds out, allies are far more valuable than hostages.
Can he truly trust his new ally?But as events unfold, he'll come to find that he might not even be able to trust himself.
