Here's a couple more book trailers I've come across recently.
The first one is for Bad Taste in Boys by Carrie Harris; it's not the best trailer I've ever seen, but it makes me giggle.
The second is for a new book from Quirk - Miss Peregrine's Home for Peculiar Children by Ransom Rigg. Not only does Ransom have an awesome name, but he has awesome skills with the camera. He made the trailer himself. And it is one damn good trailer. Quite possibly the best I've ever seen.
