The best book to start in the month of April!!!!!! 
 4.5 stars 
 Book four have a phenomenal storyline and writing style. I like this more that the other previous book. A lot of questions answered, dangerous adventures, full with twists and turns and not to mention, packed with action . Even though I enjoyed reading this, there's some part of the story that bored me. But still, I adored this one. 
 The characters? The answer is obvious, Duh. Percy's character absolutely cunning and his wittiness what make him the best character ever. Includding Tyson, Nico, Grover and Rachel. 
 What about Annabeth? Err... I do not know. She's kinda annoying in this book. 
 However, she is the most brilliant female character I ever read. NO DOUBT WHATSOEVER. 
 Highly recommend!
