Beyond excited for the next Heather Graham installment

I absolutely love Heather Graham's books and somehow she's done it again. I have no idea how she manages to write such engaging and hook-me-in books but she does. At first I was a little confused (I thought Sarah was the woman with the bloody lips and she was actually murdering the poor guy on the butcher's block) but that's not the case. The twist I love in this book is that Davey is the one who has paranormal/psychic abilities and just so happens to also have Downs Syndrome. I've read a lot of her books (not all, but a lot) and this is the first one I've encountered where the characters deviate from her standard non-disabled formula. It's so refreshing to see diversity in her books and I'm really excited to read this one and see who the protagonist is. Is it Sarah or is it Davey? (I'm rooting for Davey!)
