German Titles of Isobel Bird's "Circle of Three" Books

[Thenia]

Is there anyone who can help me combine the German books with their English editions? The German titles aren't numbered so I can't tell which book is which book's translation since most of the titles aren't faithful translations of the English titles of the books.

Any help will be appreciated.

Here are the links for the books:

Magic Circle, Magie des Lichts
Magic Circle, Liebeszauber für Kate
Magic Circle, Im Bann der Karten
Magic Circle, Die Nacht der dunklen Mächte
Magic Circle, Hilferuf aus dem Jenseits
Magic Circle, Im Reich der Geister
Magic Circle, Das Pentagramm

[This Is Not The Michael You're Looking For]

As far as I can tell, the order of the first 8 are:
1. Liebeszauber für Kate
2. Geheimnisvolle Offenbarung
3. Hilferuf aus dem Jenseits
4. Im Bann der Karten
5. Die Nacht der Dunklen Mächte
6. Magie des Lichts
7. Vollmond-zauber
8. Das Pentagramm

Can't pin down "Im Reich der Geister" but based on the translation of the title and the publication date, it's probably #9 (Through the Veil).
