Unnatural Creatures is a collection of short stories compiled by, and contributed to, by Neil Gaiman and Maria Dahvana Headley. I love everything Neil Gaiman touches, so of course I loved this, but with good reason, not just because I'm a hopeless fangirl.
I would highly recommend getting yourself a copy of the hardcover to own and cherish for years to come. This is a true heirloom collection, in my opinion. And as a nice bonus, all the sales benefit 826DC, "a nonprofit organization dedicated to supporting students in their creative and expository writing, and to helping teachers inspire their students to write".
