Zoe is only three when her mother disappears. Brought up by the aunt and uncle who despise her, she learns she has no value, unlike her big sister Kim, the real daughter on whom they dote.

She defies the odds to make it to university and forge a successful career in the City. For the first time she seems to be happy. But strange dreams and even stranger messages that appear on her bathroom mirror fuel a growing sense of unease. After falling in love with Zak, a talented young scientist, she quits her job and moves to the country to become a writer.

At first the idyllic lifestyle and newfound love bring her peace, but soon the money starts to run out and her life spirals downwards. Nothing she tries provides more than a temporary respite until she meets a very special psychologist. The secrets they unlock together help her unleash her true potential, and her life is finally full of the deep love and fulfilment she has never really known.

But will her new happiness last... or does life still have one last surprise in store?
