I recently reread this book and it was just as good as I remembered. I love how Rick Riordan took dusty old Greek mythology and made it so contemporary. The book is feels so fresh and funny. It is fast-paced, with lots of action and excitement. Percy is a very likeable protagonist, although my favourite character is the clever Annabeth. Camp Half-Blood makes a great setting. It's just a purely enjoyable, fun read and will make you want to read all the sequels. Highly recommended.
