Blech! That is the sum total of my opinion.
Not worth the time.
Not a good plot.
Not good characters.
Heck, not even a good romance and these two have fought through death itself to be together so the romance should be better than tepid, dontcha think?
This series was originally three books and while the ending was bittersweet, if a bit hurried, that ending worked. This feels very much like the old books were dusted off and it was decided that more money could be made from this series without remembering that the story is finished. Or should have been.
Sometimes a story has simply been told.
Should be left alone.
Should not be added on.
And so you're thinking well, quitcherbitchin, you chose to read the dang thing. Yes, I surely did and I regret that. These last two installments have ruined my original feelings about the series to the point where I now dislike the whole mess.
Okay, to specifics.
Tristan has returned from the Great Beyond in the body of Luke, a murder suspect whom, as it turns out, was murdered himself. There is much about how Luk-stan must stay hidden, until later in the book when he mostly doesn't and okey-dokey then, whatever.
Luk-stan and Ivy are in love and kiss. Does that sound a bit dull? Yeah, it is like that, there is no warmth or passion felt between these two. They could have been two platonic friends investigating this murder with the total lack of emotion between them. It's missing and since the overall arc is about unending, eternal, I-can't-go-on-without-you love, that is a substantial missing piece. We are told they have this love for one another, but it isn't shown or felt. Their conversations and soulful glances don't feel like two teenagers. They sound very stilted and formal, not like anyone normally speaks or behaves.
There is a large cast of characters, Kelsey, Dhanya, Max, Chase, Bryan, Alicia, Tony, about whom I care nothing. They are not developed in any way and are mostly various generic types who don't move the action along in any neccessary way. They party, they hang out, none of it is interesting and reads like the filler that it is.
Most of the plot is about the murder of Corrine(wait! who's Corrine,you might be asking, but don't worry, this whole plot which is most of the book, truly isn't important), with side bits about Beth being taken over by the also-dead Gregory and Beth being nasty, unkind, attempting murder, etc. Wow, that is edge-of-your-seat stuff, right? No. It is pushed aside so much to deal with the plot that I cared nothing about that when some action happens there, it seems stuck in, as if the author just remembered she needed to move that plot along.
This feels like the author was desperate to write more in the series, but didn't really have any new ideas for her characters so she either recycled used plots or crafted one about people that no one cares about.
All of the actual action happens in the last fifty or so pages.
So, the final book will be about Tristan losing his soul, I suppose. I should care, but I don't. I don't actually think the author does, either.
Badly done.
