Blaine Donne is a retired military special operative now devoted to problem-solving for hire. He investigates a series of seemingly unrelated mysteries that arise with the arrival of a woman with unlimited resources who has neither a present nor a past. The more he investigates, the more questions arise, including the role of the two heiresses who are more--and less--than they seem, and the more Donne is pushed inexorably toward an explosive solution and a regional interstellar war.
