In Cavallaro's universe Sherlock Holmes and John Watson had never been fictional characters, but real detectives and Arthur Conan Doyle wasn't anyone else that their literary agent. 
 Generation after generation the Holmes and Watson families had a really friendly but something happened, so Jamie Watson and Charlotte Holmes never really knew eachother. 
 Jamie dramt often to start an adventure with Charlotte Holmes and his occasion comes when he win a scholarship that sends him to Sherringford, an american school in Conneticut. It's here that Charlotte is currently living. 
 Their paths will meet when blood and shadows start to spread all around Sherringford. 
 I really enjoyed this book, maybe because I felt like it ws the perfect summer read: a pretty, cute and relaxing mistery and an adventure un ya key. 
 This story is a gender bender version of Holmes and Waston, rewritten a little bit and set in the modern days. But anyway, Jamie and Charlotte have a lot of personality traits in commons with their ancestors - even in their phisical apparence. 
 Charlotte was an interesting character. She has bad addiction and habits, and people don't help her enough... but she's auto destructive and out of controlo most of the time. If someone try to help her, the readers can be pretty sure that she will find a way to act how she prefers. 
 I liked that Jamie tries everytime to help her, even if he fails all the times: he's young and he doesn't know how to face this kind of problems. I love him when he explodes with his angry rages. 
 Charlotte and Jamie relationship was really cute, especially beacause they really need eachother. Both of them have a bad family, one all power and richeness and the other one is apart with a completely useless parent. 
 Talking about the story, what I really loved were the various reference of Doyle's works and the dark side of this novel - rape, drug addiction, broken and crazy mind... 
 I like the way Cavallaro choosed to talk about them. It wasn't really deep and too much dark, but makes clear that these crimes and problems exist and people sometimes - most of the times - act like they don't exist. 
 This book isn't perfect but I really enjoyed it and I can't wait to read the sequel.
