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.
