The Black Heart Crypt by Chris Grabenstein

4.0

Another great addition to the Haunted Mystery series. In this one, an old family feud returns to haunt Zack and friends on Halloween. I loved the appearance of more of Zack's family and the fact that the friends he made in the last one stuck around for this one. I hope Zack's mother's ghost is done appearing - she wasn't doing much for me in her attempts to make amends. Another quick and exciting read!

Thanks to the publisher for an advance reader's copy.
