Let me start by saying that I went back and forth a handful of times between three and four stars, absolutely indecisive of my final verdict on YOU HAVE SEVEN MESSAGES -- so I erred in favor of the author, going with four stars. It wasn't quite what I expected, but it was still a nice read. 
 But, let's back up a bit and start with plot. YOU HAVE SEVEN MESSAGES is the story of Luna, the daughter of a dad who is famous in film and a mom famous in modelling. Except, Luna's mom died a year ago and everyone is being mysterious about her death. What really happened on that day a year ago? Luna's dad is being sketchy -- so what is he hiding? Luna may never know -- that is, until she discovers her mom's old cell phone. And in that cell phone are seven different messages which may hold the secret to everything that Luna has been missing for the last year. 
 Okay, I'll give a minor spoiler by telling you that the "mystery" here just isn't so mysterious -- hence my indecisiveness in rating this novel. I picked this one up expecting a mystery mixed with a good dose of teenage self-discovery. And, well, the *mystery* just didn't quite live up to my expectations. 
 However, the teenage journey of self-discovery was enjoyable, giving this book a little more depth and universality. Throughout the story, Luna (who is quite the little hipster) is given a camera and she explores herself and her surroundings through her photography. She learns life lessons about love, family, forgiveness, all while meeting a boy, traveling to a beautiful foreign country, and embarking on the task of presenting her first photography show. 
 My only other slight criticism would be the writing style. It was a bit overly melodramatic, which would have appealed to me more, I think, when I was 15 -- feeling ever so emo and so larger-than-life in my tangled world of teenage emotions. As an adult, though, it just felt like it was trying too hard at times -- which didn't distract from the voice of the story, but did seem a bit worthy of an eye-roll or two.
