Ardus : a Vault Agency novel / by Jean Gilbert.

"The sting of a poisoned dart, the stab of a treacherous knife, will only lead to death. At Vault Agency, time follows a different set of rules. Though J.D. Dash is dead, Sharra Lane's troubles are far from over. When Sharra uncovers a secret identity of one of her fellow agents, little does she know that when forced to reveal it, it will save her, yet condemn her. For that knowledge holds untold power, and there are those on Ardus who will do anything - even kill to keep it hidden. Follow the Vault Agency team as the continuation of the search for Sharra's nemesis takes them to the future, to Ardus, where family treachery runs even deeper than Sharra could ever imagine"--Back cover.
