This book is now out in paperback, and you can even get a used copy of it if you like. The second in the series, "Hollow City," will be coming out later this month, and I can't wait to read it. (You can pre-order it at Amazon.com.)
The first book is also available now as a graphic novel, and author Ransom Riggs has come out with a collection called "Talking Pictures."
Okay, so, what's so special about the book? The premise is startling and original, the characters are really well done, and the photos are a great addition, but then...the plot is perfect for a YA novel:
A teenaged boy, unhappy and unsettled, with parents who don't understand him --- all the elements right there! --- finds out his grandfather, who loved him but was dismissed years ago by the boy and all the family as crazy, was not crazy after all. So the boy travels to an island in Wales where he meets Miss Peregrine and her collection of peculiar children.
Sorry I can't tell you any more, because to do so would spoil the story for you. So, read it for yourself! I think you'll like it.
