The Haunting, by Lindsey Duga

Twelve year-old orphan Emily has a dream come true, when the wealthy Thorntons adopt her and take her away from the nasty orphanage to which she is consigned.  Life at her new home is a dream:  a huge manor house, fine food, pretty new dresses, and best of all she gets to keep her pet mutt Archie.  There's even an odd little girl named Kat who keeps suddenly appearing and disappearing, who shows Emily around the vast estate.

But then strange things start to happen:  thumps in the night, falling bookcases, exploding windows, and a brutal sudden chilly air that keeps reappearing.  What starts as oddities becomes life-threatening.  Emily and Archie must find out what haunts the place and how to rid it of its ghosts.

Extremely formulaic middle reader, full of all the usual suspects:  abused orphan, stepparents with secrets, gothic mysteries, ghosts, and that friendly canine companion.  For the target audience, the story's lack of ambition is probably fine, but this is one of hundreds of similar books and I don't see how this one is going to stand out in any remarkable way.

Disclaimer:  I recieved an ARC of this book from the publisher in return for an unbiased review.  The book is slated for release on February 4th.
