A Very Bad Thing: Jen’s Quick Take

- There’s a LOT going on here: five narrators, a police procedural element, an epistolary story-within-a-story element, and some soap opera/ family secrets vibes

Spoiler Review of A Very Bad Thing
Spoilers will be protected, so you can read this up to the protected area if you have yet to read the book!
Where to start?
A Very Bad Thing Starts Off Strong
Famous writer Columbia Jones (I thought of her as “CoJo” in honor of wildly popular and controversial Colleen “CoHo” Hoover) is on a book tour.
She’s accompanied by her only child, daughter Darian.
Also in her entourage? Riley Carrington, a journalist who is writing a profile on Columbia that will be released in conjunction with Ivory Lady, a movie adaptation of one of Columbia’s books.
Columbia has a stalker, who turns up at her Denver book event. Then Columbia turns up dead in her hotel room.
Who did it and WHY?
Then Things Get Really Complicated
A police detective gets the case. Darian finds some unfinished manuscripts belonging to her mother. Secrets come spilling out.
What was Columbia hiding?
What’s with her mysterious new will?
What do all these narrators have to do with it all?
It’s better to go into the book without knowing too much, so I’ll leave it at that and go into depth in the spoiler section. There are a LOT of spoilers, so you can read some if you want without getting the final reveal.

I don’t get the ending at all. I didn’t understand how to get into your spoiler section. How did Liam get on the island? Is Mason another bad guy?
The book hasn’t come out yet so I have the spoilers protected but you should be able to see them by creating a Grow account and I think you can use Facebook.
Mason was the Big Bad and manipulating Liam. As for how Liam got onto the island, I am away for the holiday without my notes, so I can get back to you!
Who was Mason’s mom? Knox said he had a girlfriend before he met Devon but that she was definitely not pregnant when he left her.
You’re right, I checked and Knox does say that in chapter 55: he dated a nurse and would have known if she were pregnant.
So either the nurse didn’t tell Knox she was pregnant, or Mason is making it all up, or the nurse got pregnant by someone else.
Mason was fueled by anger that Knox had ditched him and his mother and ended up in prison. Near the end Mason says that his mom died of a broken heart.
Liam also says he’s Knox’s son during the standoff in Maine, but in his email to Mason at the end, Liam calls Knox “your dad” and says “Riley and Kira will figure out they are related to you.” Liam tells Mason that he documented everything.
I don’t know!!! It’s definitely unclear. I will add this question to the post and maybe someone picked up something we missed in those 500 pages!
I enjoyed the book because I like mysteries. I was totally confused by the ending and I kept rereading the last few pages. I just couldn’t figure out how Mason was related. I’m so glad I found this site.
SO confusing. I added even more details to the post on who was related to whom and how. I think I got it right but wow it was confusing.
I enjoyed the book but am confused about a couple things. Maybe someone picked up on clues I missed:
How did Mason know all these facts about his dad (Knox), Columbia / Devon, etc that weren’t disclosed until after Columbia’s death and / or at the Will reading? He presumably got the rat poison three weeks before he / they killed her so was planning this for a while?
Why did Knox show up in Denver and suddenly leave the auditorium?
Hi Tami!
I am not sure – this book was a LOT but I enjoyed it.
Maybe Mason found out Columbia’s real identity on his own? Or Liam the hacker told him? And I’m not sure why Knox left.
If anyone has ideas, please weigh in!
