This was a free Kindle book I grabbed for my son. I decided to read it first to make sure it was appropriate. Also the premiss sounded kewl, a modern day sherlock Holmes mystery. Unfortunately the writing is abysmal. The three main characters are fourteen and talk in a mix of outdated and multi region slang. It made for annoying reading. The Sherlock Holmes connection seemed random, he comes out of his old pipe one of the kids happened to pick up. I read far enough to determine that the book was kid friendly, about four chapters. Then I couldn't take it any more. I seriously doubt my son will like this book any more then I did. It is going in my rare couldn't even stomach it enough to grin and bare it pile. Don't bother.
