The A Ghost of Granny Apples series is one I stumbled upon and I frequently forget about, but always enjoy.
Emma Whitehouse has gotten used to dealing with ghosts since she discovered her ability to see them two years ago. She finds herself contacted by an old friend who thinks she is being haunted by her dead husband and wants Emma to just take care of it.
Emma finds out that the daughter has been acting strange she decides to look into it and finds herself tangled up in another mystery.
It's a fun book and while I did have an idea what was going on, it was an enjoyable read.
