Ess decides to supplement her income by reading auras professionally, but when her first client has no aura at all, it catapults her into an entirely different profession: psychic detective. Sometimes helped, sometimes hindered by her ebullient sidekick, Professor Oz Dawkins, she needs to hunt down a missing son. Love never runs smooth, especially mixed relationships. When one partner is a young girl in the first flush of love, and the other is a vampire desperate to be human, it's even harder. Neither family approve of the match, and just how do you make a go of it when one of you works days and the other nights? Set in London, this modern Romeo and Juliet story has a cast of demons, students, succubae, jobsworths, vampires, and supermarket shelf stackers. Lives intertwine as they race helter-skelter towards a dangerous climax. Can love survive? Can anyone? Thicker Than Water is the sequel to The Young Demon Keeper, the Amazon Breakthrough Novel Award semi-finalist 2011.
