Series 1

Abby and her sister Zara are not real people. They were made, created by pan-dimensional beings - the Grace - to help save space and time. The Grace gave them special powers. With just a thought they can be anywhere or when in the universe. They can affect people, see into their heads, influence their thoughts. . . They're still learning what they can do. Now they've completed their mission, the Grace have left them to fend for themselves. The universe is dangerous, unpredictable. Abby is not so good-as-gold as she appears. Zara's already destroyed a whole world. And they've only got each other.
