Timeless: Part One — Monique Martin

In the thrilling first part of the two-part Timeless saga, Council for Temporal Studies operatives Simon and Elizabeth Cross return from another mission back in time — only to find themselves trapped in a world they don't recognize. The evil Shadow Council has taken control, governments have risen and fallen, and even their own pasts have been radically altered — and to make matters worse, the memories of their previous lives are fading with every passing moment. Simon and Elizabeth must set things right before they forget who they were meant to be and lose everything, and everyone, they hold dear — including each other.
