'A dark, twisty and addictive read that you will struggle to put down' LISA JEWELL, multi-million copy bestselling author

'I have loved Jessica Knoll since I read LUCKIEST GIRL ALIVE a decade ago, and HELPLESS, to me, has the same atmosphere and completely addictive nature ... This isn't a comfortable novel - there is genuine tension about whether the relationship at its heart is tender or twisted. But the question is asked, and explored, and I think that's why I liked this so much. I'm also a sucker for books about writers, and there's a really great examination of the morality of using real life for fictional creations' ABIGAIL DEAN, the Sunday Times bestselling author of Girl A

'If Jessica Knoll writes it, I'll read it. The pages of her books seem to crackle with electricity and she's an utterly fearless writer.

Dark, daring and deliciously sexy, it takes an unflinching look at power and privilege, and the ways in which we efface ourselves for those in control' KIA ABDULLAH, bestselling author of Those People Next Door
