This is a very readable book - that's one thing in its favor. There is an aura of creepiness about it, but all too soon it veers off into Lifetime Movie territory, and has far too much similarity to McMahon's first book, which I read a couple years ago. I don't find the characters particularly likable, and I am really offended by (spoilers coming up; if you plan to read this book do not read the rest of this review) -- offended by the ease with which Lizzy returns for the purpose of forgiving her dead father.
The denouement is anticlimactic; the characters, except for the young Lizzy, are for the most part unsympathetic, particularly Tock. Bleh. A disappointment. I gave it three stars because it was, for the first 2/3, immensely readable.
