Time is both ally and enemy as TID agents Brett Hostam and Krista Lysander leap into the past. Their mission? To unearth hidden truths buried in the chaos leading up to 9/11. The Russian TID has its own operatives, including a specialist GRU team called Zodiac. Why are they in the USA?

The agents have to confront the enigmatic Russian GRU team known as Zodiac. They lurk in the shadows of the present, but with strange links to Krista’s secretive past. Krista's parents, who were once TID operatives themselves, hid their family in 1970s California. Sag, who might be a Zodiac team member, is there for some reason, is it coincidence or something more sinister?

Current operatives clash with past and future time travelers and their management. Every jump poses physical threats, and they appear to be harming the agents' health. History cannot be changed, but the future can be.

TID needs more agents for an endless list of missions, but some of those are politically motivated. Four nations have chambers for long time jumps. They have hidden features too. Agents are left-handed and provided with local jump devices. Will the agents uncover the truth before it's too late?

Join them in a heart-pounding race through time where the past is never what it seems and the danger is always one step ahead.
