Rick Riordan never fails. This story was amazing! I love how as I'm reading any of the Percy Jackson books though they're fictional I can picture everything. I can picture the scenes with the monsters fighting and create images in my own mind. Plus I LOVE the characters! Rick does such a great job of constantly building each character up (or down) to be their own person. Having relevant characters in a book is HUGE to me and he does this perfectly. 
 Percy - Never fails. Even though he kind of jumped in on a quest of his own this time he was successful. I wish he'd put more time into his training though to become extra badass! I love though how they show how important education is. Despite how many schools he gets kicked out of Percy always shows that his education is important. 
 Grover - Oh man. We weren't really WITH Grover majority of this book. But we felt his struggles. It cracked me up though the cyclops playing with him and thinking he was a girl. Imagining those scenes in my head had me cracking up. 
 Annabelle - I love her! She's a girl badasss. Though her and Percy may argue and fight though their friendship always prevails. 
 Tyson - Is our new friend in this book! He goes to school with Percy and is constantly being bullied and pushed around. Percy being the good guy he is though ames him under his wing. Only to find out they have a lot more in common than meets the eye. 
 I wish I could write better reviews without completely spoiling the book. So in this case I'm just going to tell you to GO READ THIS NOW! If you're not on the Percy Jackson train just yet please hop on because it's an amazing and thrilling ride.
