I read the Ninth Key, no. 2 in Meg Cabot’s Mediator series. The premise is this girl sees dead people and helps them on their way to the after life. Cabot’s Suze is an endearing 16 year old. Also, her dead father pops up to give otherworldly advice and a very handsome ghost lives in her bedroom.
Fast paced and silly and charming. Really can’t miss on this series.
