I read this while on vacation. This book reminded me a lot of "The Girl on the Train" mostly because it was set in Great Britain, but more so because each chapter was from the perspective of one of the two main characters (both women).
The story is about these two women who live in this minimalist-style house that has a ridiculous amount of rules in keeping with the minimalist theme (like, no clutter, etc.). The women lived there at different points in time and their stories unfold throughout the novel. There's a murder (of course) with a twist (of course), but I thought it was pretty well done.
My rating: 4/5
