Sleeping in Flame uses the classic Jonathan Carroll elements: there's Vienna, love, reincarnation, magic, a writer and so on. That should sound familiar to anybody who has read Carroll. However, despite the familiarity, I found Sleeping in Flame simply fantastic. I've read, what, nine of Carroll's books so far and of what I've read, it is probably my favourite.
Walker Easterling is screenwriter living in Vienna. She meets a fabulous woman, falls in love and then, magic starts to happen. It's not warm and fuzzy magic, but strange and apparently dangerous. Walker investigates and bumps into curious cast of people, some familiar from the other books in the same continuum Wikipedia calls the Answered Prayers sextet.
It's a lovely story and I enjoyed the way it recycled old fairy tales. The only downside about reading this book is that there's one less Carroll book left for me to read... He's one of the most constantly great authors, every book I've read from him has been good. Highly recommended, this one's a good starting place for those new to his works.
