It took me a week to complete this book. And I did it. Yay! 
 The plot in the narration was the most interesting I'd ever read than the last two books that I'd read not so long ago. In this book, the characters travelled to many places to help Nico that had been captured by giants, and also tried to discover the statue of Athena that could save the both Camp Half-Blood and Camp Jupiter. 
 The characters, as always, soooooooo good. The character development indeed improves. They were getting stronger and stronger. Particularly, Hazel and Piper. 
 In this book, a lot of questions answered. For example: Why Hazel thought Leo was Sammy. It was a predictable question, but hey, the plot twist still shocking. 
 I actually have nothing to review about my thoughts and feelings on this book because there are the same T&F for the first two books.
