Maybe a 2.5. Some of the writing is interesting and the mystery isn't bad but the characters in this are rather unlikable. I feel like I needed a hot shower after some of them and the lead spends far too much time whining. Yes, Alex, has stuff to whine about but she retreads the same ground over and over. There were other issues I'll put last under a spoiler warning.
It opens with Alex having sex with her ex. That sets the tone for Alex as a character, with no more judgment about men than a squashed hedgehog and pretty easy to boot (That's not me slut shaming her. She spends a quarter of the novel slut shaming herself. Be prepared). Alex's mother is a talent artist who is also bipolar and tends to destroy her art in her depressed phases. Alex has no idea who her dad is. In the middle of the sex, Alex starts 'seeing strange rituals' leaving you wondering if this is a light paranormal mystery, is she nuts, high, what. Alex tries to get information out of her mother and just when it seems like Mom is going to tell her, Mom commits suicide.
Alex goes back to wine country to talk to her step father only to find out her mom was keeping even more secrets from her. Alex had a little brother Dylan, whose body had just been found decades later. Alex has no memories of her brother and her ex, a psych professor (Alex is a grad student studying why people have the religious beliefs they do), had an explanation for why. Alex finds herself between Tim (ex) and detective Daniel Reed who she knew as a child. While Alex seems to be getting closer to her step sister, not everyone is happy to have her back at the family winery, including Reed's father.
Someone, in fact, is killing people and doing a good job of making Alex look insane and deadly. It's not helping that everything she finds out about her mother gets worse and worse as she goes. And Alex still has no answers as to who her father is or who Dylan's father was and why killed him. I don't want to get too much into that since it would be a major spoiler.
I will say the mystery wasn't completely terrible but a bunch of unpleasant, self-serving wealthy wine-making families just didn't make for compelling characters. Alex vacillates between being a 'strong' female and being a whiny twit who needs Reed or Tim to take care of her. I didn't really care much about her. Or Reed who thinks it's perfectly fine to start sleeping with someone who was at first a victim then a potential killer in spite of the fact he's the one investigating the case. So real professional there. In fact this story would have been improved ten-fold without the icky romantic subplot. As to why it was so icky, well look below but keep in mind there will be spoilers. If you don't want them, stop reading here with my thoughts that there have been better books by this author.
Spoilers....
Okay so when it comes down to it there are two spoilers. One is that the story used the trope of a person calling up to say they're about to reveal a big secret 'but not over the phone' and end up dead before they do, not once, not twice but three times! How ridiculous is that? In fact there was nearly a fourth but that one lived to tell the tale. Granted we're never sure if Mom killed herself or someone killed her once Dylan's bones had been found and that annoyed me too.
The other big one is it was possible that Alex's mom had been sleeping with Reed's much older brothers. Somehow this does NOT put Alex or Reed off sleeping with each other even though he could have been her and Dylan's uncle. It's not until it's suggested that her mom had also slept with Reed's dad that it occurs to them oh hey this might be incest. So not only do we have Reed being very unprofessional about sleeping with her in the first place (and at least his partner calls him on it) he's not too bothered about what their relationship might be. Yeah like I said if the whole romantic had been round filed before this saw print the story would be been stronger and less gross.
