The phrase "in late out early" is often times referenced for writing introductions. You want to start your book as far into the "action" as you can with it still making sense, and end the scene early enough that your readers are left wanting more. This book started a little too late and left a little too early. We start off in the drive after Violet's funeral to pick up clone Violet. From there we meet her and then there's a time jump of 5 years and Cate and clone Violet are in high school the day Samantha is pronounced murdered. The relationship between Cate and Violet and then the relationship between Cate and clone Violet is what drives this book. Cate will make decisions based off of her feelings towards her dead sister's clone or her sister proper. But we never get to see Cate and Violet interact, don't get to see the awkwardness immediately following clone Violet being brought into the house, the angry fights that must have ensued for a grieving and confused not yet teenaged Cate being told to pretend that her sister didn't die. Cate tells us these things happened, sure, but we never get to see them. So when all I have to go off of for Cate and clone Violet's relationship is how I see them interacting after Violet's under suspicion of murder? I don't really understand where Cate is coming from in her decision making.
