To be honest, I never really got hooked into the Percy Jackson series, though I know mast people are. However, I would say that this book is good because it is the introduction of the series and it gets you kicked into the series. My favorite part of the book was when Percy joined Camp Olympus and got introduced to his half brother, who turned out the be a cyclops. Over all, I think that this was a pretty good book and a great start to an action packed series.
This book is well suitable for kids that are in 2nd to 5th grade. This is because it gets them excited about joining middle school, which is great. even though the book is about NIkki getting bullied, it also shows how she adjusts to the new school and make new friends, which comforts kids that move to new schools. It talks about common things that happen at school, like having a crush, bullying, making new friends, arguments with your siblings, etc. It is very funny and encouraged m start writing a diary too.
