The Past is Their Mission. And The Future Their Destiny. At Vault Agency, time follows a different set of rules. Giving up their former timelines for a higher purpose, the illusive agents set about 'fixing the past for the betterment of the future,' using the powerful mainframe of the Vault to shift back and forth across time right under the noses of the unsuspecting public. From the moment Sharra Lane, the newest recruit, came in contact with the Agency, unexplained things started to happen. Life became anything, but safe. Now with the Agency out of balance with an inside enemy on the loose, Sharra must find a way to make it right, or risk losing what she desires the most.
