She wants to escape the past. Is she doomed to repeat it? In the spectacular sequel to Subject Twenty-One, Elise and her friends have unearthed the truth that has been kept from them their whole lives and escaped the Museum of Evolution - but at what cost?

'An unputdownable exploration into the ethics of science' Buzz Magazine

After a perilous escape, Elise and her companions have made it to the safety of the secret fifth base, Uracil, but her family is still in danger. Desperate to secure them passage and a safe place to live, she makes a deal with the leaders of Uracil - she'll become their spy, jeopardising her own freedom in the process.

But first she has to help rescue the next Neanderthal, Subject Twenty-Two.

Twenty-Two has never left the confines of the steel walls that keep her separated from the other exhibits. She has no contact with the outside world and no way of knowing why she has been abandoned. With diminishing deliveries of food and water, she has to start breaking the museum's rules if she wants a second chance at living.

One belongs to the future and the other to the past, but both will need to adapt - or neither will survive . . .

About the Author

A.E. Warren is the author of the Tomorrow's Ancestors series, which consists of Subject Twenty-One, The Hidden Base, The Fourth Species and The Final Rising.

After spending eight years working as a lawyer, she began to write in the evenings and early mornings as a form of escapism from life in a very small cubicle with lots of files. She self-published her first novels in her spare time, which were picked up by Del Rey UK which is the science fiction/fantasy imprint of Penguin Random House.

She is an avid reader, occasional gamer and fair-weather runner. She lives in the UK with her husband, daughter and hopefully, one day, a wise border terrier named Austen.
