This is definitely an eventful book. "Constellations of Scars" follows Amelia Weaver. For unexplained reasons, she grows pearls on her skin every month. Her mother keeps her shut inside the house, restricting her freedom. One day she decides to escape and try her hand at the real world. She ends up working for a freak show, though they are unaware of her own oddity.
Let's start with the characters. Amelia herself is perfectly acceptable. She doesn't have any noteworthy character traits, or anything to help her stand out besides the whole pearl thing. However, her motivation is clearly defined and all of her choices make sense. Gabe is probably the best character in the book. His backstory is interesting, and his somewhat reclusive demeanor is off putting without being unlikeable. Unfortunately, most of his character development happens within ten pages. Peter is... interesting. I'll talk about him in the spoilers section.
The best part about this book is the writing. It keeps the reader engaged the whole way through. While the descriptions are detailed, the author does not dwell on them long enough to bore the reader. One interesting thing about this book is the chapter length. While there are long chapters, there are also chapters that only last a few pages. I found that this kept the story at a fast pace, further keeping me involved.
The plot is the main failing of the book. Spoilers from here on out. It starts off strong, setting up themes of isolation and hiding. Several conflicts were set up, most notably Amelia's mother and the possibility of the world finding out about her secret. However, all of these conflicts are suddenly solved halfway through the book. From that point on, it shifts to a thriller about Peter secretly being a serial killer. I'm not kidding. There are hints that Peter isn't as nice as he appears, so it doesn't come out of nowhere. However, it drastically shifts the course of the story, to the point where it feels like two separate stories.
Despite this criticism, this wasn't a bad book. I enjoyed myself while reading it. Furthermore, it's a quick read (perfect for car trips or bedtime). If you're looking for an engaging story with twists and turns, this is for you. If you're looking for a cohesive story with interesting themes, this book isn't for you.
