Legacy (Thaumatology, #3)

All Ceridwyn Brent wants is a normal life, well, as normal as it gets when you are the only living sorceress in the world, your lover is a half-succubus, and you have a werewolf for a mate. Work is keeping her busy enough; she is trying to capitalise on her research with her boss by building a power generator which uses magic to generate electricity, and she has a PhD thesis interview to get through so she can finally be Doctor Brent.
Then mysterious, dark figures are seen watching the Battersea pack, paying particular attention to Ceri. The Greycoats, the supernatural branch of the Metropolitan Police, turn up to talk to Lily because men have been dying, apparently the result of a succubus feeding on them. To make matters worse, Lily is having dreams about the deaths and is starting to believe that she might be responsible. As Lily's control over her demon side weakens, and it looks as though her father may have returned to Earth, Ceri must face off against the dark magicians pulling their strings from the shadow world under the bright face of London.
As an added extra, included in this book is an unpublished short story, Black Moonlight. Ceri, Lily, and Michael go to a rock concert where Michael's half-brother is the base player.

I'm a computer programmer who has been writing fantasy and sci-fi since I was fifteen. The Thaumatology series is, therefore, the culmination of 30 years work! Wow! Never thought of it like that.
