I do believe I like this series better than the other by Victoria Laurie...and I really like that one, Abby Cooper - Psychic Eye. Both have great premises for the main characters and the 'sidekicks', along with superb stories to go with.
DEMONS ARE A GHOUL'S BEST FRIEND turned into more than a ghostbuster book. This one scared the bejeezus out of me at certain points of the story. The ghost that ghostbusters, MJ and her team, is to 'bust' is known as Hatchet Jack. He had been haunting and scaring the rich kids at the private school of Northelm on the shores of Lake Placid for over 30 years. The more the team learns and connects with the ghost/demon, the less they are liking the job. They also know that they really have to get this guy sent to where he belongs...and not the good place either.
