The prize went to The Madman's Daughter, by Megan Shepherd.
Which I LOOOOOOVED:
I really, really enjoyed this one: it works as historical fiction, as science fiction, as a horror story, a romance, a coming of age, and as a retelling of H.G. Wells' original. The changes that Shepherd makes, the twists she introduces, they all feel organic and they play off the original and change it, but in ways that complement the Wells, if that makes sense. It changes it without trying to replace it or diminish it, maybe? Whatever it is I'm trying to say (YEESH), it's TOTALLY engrossing, and I TOTALLY DUG IT.
