The series I am searching is about magical creatures who, in this alternate reality, came to our world a few years ago through some sort of portal. Basically every magical creature you can imagine from popular fantasy tropes is possible. The protagonists are three sisters - a witch (looking like a human), a catwoman (either fully human or fully house cat - not Anime-style) and a vampire. Throughout the series they become acquainted with a lot of other magical creatures, of which the following pairs were important:
- the witch had something going on with a male dragon and an incubus
- the catwoman had something going on with a male human
- the vampire had something going on with a female werewolf
They were supposed to find magical amulets or something similar which would lead to a catastrophe both for the magical and the mundane world if they ever were united at the same place. Some evil power was trying to get all the amulets to throw both worlds into chaos.
The series can't be much older than a few years. Like with a lot of series I stopped halfway through when there were no new books coming out for some time and would like to continue if I find the time again. I think there were supposed to be 9 or 12 books.
I've read the books in German and the main character from each book changed with each book between the three sisters so that for example every third book was about the witch. That's also why I think there was supposed to be a multiple of three as the final amount of books in the series.
Can you help me remember what this series is called?
