Family care lawyer Lilly Valentine's life is demanding enough. But when she is begged for help by Anwar Khan after his teenage sister commits suicide, she finds herself dragged into a community terrified by a self-styled vigilante group vowing to protect it's women - by any means necessary...

Treated with extreme hostility by the girl's family, Lilly is about to jettison the case. But when the police turn up and arrest the dead girl's younger brother for her murder, she's knows she's already in too deep.

Together with her new assistant Taslima, Lilly gets caught up in the sinister world of a self-styled vigilante group vowing to protect the 'honour' of the women in their community - and punishing those who 'stray.'

When another young Muslim girl disappears, Lilly knows it's only a matter of time before the group take the law into their own hands. But with so much in her own life at stake, has Lilly finally taken on more than she can handle?
