This was a really interesting blend of historical fiction, mystery, thriller and a ghost story. More importantly, the fantasy aspect, while chilling and intriguing, does not detract from the rest of the story, but expertly adds depth and mystique to Max's plight. I do love a good duel time story, so this was right up my alley. The story hops back and forth from 2004 in London and Vienna to 1938 Vienna. The snippets in the past are quick and give just a glance at Annabell's life with hints of clues of what is going on so we never know much more than Max. At first, Max seems like an ungrateful son, but as he figures out his mother's past his character as well as Annabel's is explained. Oskar was the most surprising character for me, another mystery to unravel, but I loved his gentle and easygoing demeanor. Overall, the mystery building was well done continually throwing me in different directions and the suspense is tightly woven all the way through. The ending threw me for a huge curveball, also. This is not a story where everything is tied up all nicely, the chilling ending definitely places this book squarely in the thriller category.
