Two girls. Two centuries. One machine that broke the rules of both.
Ava Cole lives in 2119. She's brilliant, guarded, and gets into trouble without trying. Her father built the Meridian a time machine to find her mother, who disappeared in its first test before Ava was old enough to remember her face.
One fight. One impulsive decision. One step into a machine she was never supposed to touch.
Now Ava is stranded in 2019 London with no money, no plan, and no way home.
Emma Calloway lives in 2019. She's warm, sharp, and hasn't figured out what she wants yet. When a strange portal yanks her into the future, she lands in a century she doesn't recognise and a life that isn't hers.
The problem: Ava's father thinks Emma is Ava. And Emma is just smart enough to keep it that way.
Two timelines. Two love stories. And somewhere between them, a secret that could unravel everything.
Some doors shouldn't be opened. They walked through anyway.
