I am so excited to read the entirety of this book! The cover is awesome and definitely has shelf appeal. The sister dynamic between Stella and Ellie is an interesting one to explore and to see how it meshes in with the thriller aspect of the book is interesting too. This first look reminded me of A Good Girls Guide to Murder a lá small town disappearance/murder mystery vibes, which is awesome. Recently I have been loving YA thrillers, so this seems right up my alley!
