"The Lightning Thief" was AMAZING!!!!!! It was about a 12 year old boy named Percy who finds that he is a demi god. (Which means half-human half-god). It's not safe for a demi-god like him to be in the world where monster's can attack him, so he goes to a camp that is just for people like him. But Zeus's lightning bolt has been stolen, and Percy is the suspect! Percy along with his friends Annabeth and Grover must go on a quest to find the lightning bolt and prove that Percy never took it. The author is Rick Riordan and there are 375 pages in the book. This book taught me lots about mythology. This is also a series of books, it's called the "Percy Jackson and the olympians" series. I would give this book a rating of 5 out of 5 stars.
"Island of the Blue Dolphins" was interesting. It was about a girl who spends 18 years of her life on an island by herself. She knows how to find food and how to live on her own, but there are also many challenges she must face. The book, in my opinion, was really exciting at some parts, and then boring the next. The book went like this the whole way through. The author is Scott O'Dell and there are 178 pages. My rating would be 3 out of 5 stars.
