The second installment in the Wayward Children series by Seanan McGuire, I simply couldn't wait any longer to dive in. 

This story is following Jillian and Jacqueline (you meet them in Every Heart a Doorway), twins who were born to parents who should have never been parents, and are forced to attempt to mold into the visions their parents had for them. When their door appears, they head off to a world that holds a different life for each of them - the Moors.

Jacqueline, now going by Jack, easily decides to become an apprentice to Dr. Bleak and finds her time in the Moors full of learning and loving. 

Jillian, now going by Jill (get it? Jack and Jill), decides to stay with the "Head" of the Moors, a vampire, eager to grow and become an adult so that she can find eternal love with him. 

This novella will give you a beautiful, yet heart-breaking background into their lives and their time in the Moors, which is obviously before they arrive at Eleanor West's home for Wayward Children.

I don't think this book was "as good" as the first in the series, but I don't want to say much more as to not give too much away.
