Roughly a year ago I have read a book about a Succubus in current day London. Basically she was a human that transformed to a Succubus in the night and when she transformed it was as if another version of herself took over control over her actions. As a Succubus she could fly and had a magical way to influence men that slowly drove them into madness.
There were other Succubi in the story and for some reason they were trying to convince the protagonist to become an ally. I think she was supposed to be very powerful once she mastered her powers.
In contrast to the other existing Succubi she was reluctant to use her powers, because as a teenager, when she realized her transformation she started to hurt people in her vicinity. Therefore she built herself some sort of cage by electrifying the lock on her home at the time of her transformation with no way to turn it off so that her other self couldn't escape.
Being able to turn into a Succubus runs in the family, though her mother was left out. Her grandmother gave her some pills that would help with the transformation, though she can only take them at a certain time. Otherwise they would amplify her need to transform instead of suppressing it. Her grandmother died and she finds a stash of the pills at the house of a few older neighbours. I think the grandmother lived in Germany when she was still alive.
The protagonist probably killed parts of her family when she was in Succubus form. I think her sister died and later her parents in an accident. But she can't remember what exactly happened.
It felt mostly like an introduction, which is why I feel it was the first book of a series. I've read it in German. The book was quite new when I read it.
Random things I still remember:
- she had a cat
- making breakfast for herself and the cat consisting of porridge was described quite often
- later the protagonist gets a cage in her attic in addition to the electric door - I think she uses this to show someone she likes in which way she transforms in the night
- the book starts with a different Succubus convincing a man to jump from a roof and thereby killing himself to show his love for her
I can't remember what the book was called and I wanted to have another look at the series. Can you help me remember the name of the series?
