Holy crap-a-doodle! Even though I can't find a book store selling it yet, Strange Things Happen has already been released in Canada according to http://www.harpercollins.ca. In fact, if you search for the book on that site you can "browse inside" and read at least ten full chapters from different sections of the book. You can also see some pictures, a full table of contents, the acknowledgements and a list of photo credits. Those who are chopping at the bit to read the book can set their teeth into a pretty large chunk of it. Enjoy, but please keep in mind the Strange Thing virgins who are saving themselves for the real paper and ink experience. Be careful not to drop too many spoilers. I haven't read more than the table of contents and I had to stop myself from saying too much in this post.
HA! I did a little edit to correct a honky spelling error in the title. Now it looks like DM can't spell. Sorry dear.
