It is a really good book about a girl called Friday Barnes. She was called Friday because her parents thought she was born on a Friday but she was actually born on Thursday. Her uncle, Uncle Bernie works for a police thing and he gets a case about a stolen diamond. She solves it and gets a reward of 50,000 dollars. She then decides to use the money to send herself to the most exclusive boarding school in the country, Highcrest academy. When she gets there she meets a boy named Ian Wainscott, who hates Friday and loves Pranks. Not only that Friday has to solve many mystery’s at Highcrest Academy, including one on a swamp yeti. So far it is a really good book. I would recommend it for ages 10+ because of some of the words wouldn’t be understood by any age lower.
