The Wife Upstairs by Rachel Hawkins

I didn’t realize (at first) that this was a modern-day retelling of Jane Eyre (which, despite good intentions, I’ve not yet read). That kind of bummed me out, because I’d ordinarily want to have read the original novel first before diving into something like this. Once I knew what I was reading, I toyed with the idea of setting it aside, but I was already so invested in the story that it would have been impossible for me to do it.
