The Wife Upstairs by Rachel Hawkins (spoilers/plot discussion)
I found the main character really unlikeable. All she did was complain about everyone around her (in addition to stealing/committing murder). She was just this really skeevy, unsavory character. She was one of those people who believes that they're morally superior for being poor, yet obviously she doesn't resent Eddie, who is rich, because... it would benefit her if they were in a relationship? Also, at the end she also comes into wealth... so is she now also a bad person? Her entire motive for robbing others was, "They don't deserve these things, because I am poor, and they are rich. They won't notice if I take this stuff." Yeah pretty sure you'd NEVER get away with this in real life. I'm basically fine with books with unlikeable characters, but when you can tell the author is basically on their side, they become insufferable. Scarlett from Gone with the Wind is basically the mecha-cunt of American literature, but she's tolerable because ALL the other characters and the author openly acknowledge that she's a terrible person.
Also, I feel like the "Jane Eyre" metaphor was pretty weak. The only strong parallel is that Edward locks Bertha upstairs. If anything, it feels more similar to Gone Girl - the seemingly perfect wife is a sociopath who revenges herself against anyone she feels has "wronged" her. Her diary was actually unreliable/used to manipulate others. The husband was actually the good guy. They choose to remain together because in a weird way they complete each other/love each other. It really doesn't make sense because if this was JANE EYRE, Jane and Edward would be soulmates. He openly says that Jane's and his souls are the same, yet he still chooses Bertha... what? Also, Jane Eyre's Jane and Helen were morally righteous people (Helen even more than Jane). How is Wife Upstairs Jane even remotely similar to either of those characters?
The ending made no sense. Jane: "Omg, Eddie gave me all his money to buy my silence." How would he know that he was going to have to burn the house down and need to buy your silence before it actually happened? How could he have known he'd be overpowered? Also, if Eddie and Bea are now penniless, how are they supposed to survive for the rest of their lives? They can't work, they're presumed dead. Also, how did Eddie even know that Bea had killed Blanche, when he didn't see anything, thus setting the whole plot into motion?
I'm probably just reading too much into what's basically a throwaway thriller novel, but this all irked me. There's more I could complain about but I'm just going to stop here. These types of thriller novels are all basically mediocre/the book equivalent of Lifetime movies, but they're still at least entertaining.
