What I think about it:
At first: I loved the vintage photos and the formal style of the book as a whole. There is something appealling about the cover which makes you want to start reading immediately ;) Also there's the name of the "Bird" - Alma LeFay Peregrine - embossed to the book cover, which is another sign for me that shows how lavishly this book was made.
So the pictures are the main part of it. The story was woven around them and the author did a good job, but I had the feeling it couldn't reach the creepiness, the exotic feeling or the expressiveness of the photographies. They are all just weird and wonderful :)
The idea of the story is good though, and it's thrilling and all, but sometimes I wanted to shout at Jacob ;) The story line was predictable from time to time and Jacob was just so slow when it came to understanding hints from other people.
Last but not least I liked the ambience of the book. Walking through the storm and rain on this little island, the abandoned orphanage and the atmosphere of the 1940s. Added to all that there's the peculiar children which make the reading experience dark and creepy enough without having the the spine-chill as the main theme of the story. So all things considered, it was a nice read, different from other books, and I enjoyed most to flip through the pages taking a closer look at the vintage pictures. I'd recommend it to anyone who likes fantasy and books for teens.

The peculiar children are going to travel Germany:
1. Canchita
2. sosa76
3. Qantaqa
4. Kiki66
5. Mary-T
