Hello Readers, This is a wonderful book - the fifth in the series of Percy Jackson which was recently released. This book revolves around greek mythology, and some knowledge about this subject could prove helpful while reading this series. As this is the last book in the series, Percy Jackson, who is the main protagonist, and his buddies are locked in a final battle with a Titan who is none other than Lord Kronos. The battle ends with the defeat of Kronos, and thus ending in the saving of Olympus. In this book Percy and Annabeth also pair up to become a couple. This book reminded me about the Harry Potter series, though there cannot be any direct comparison between the two distinct sets of stories. The only thing that I could think of is that Percy Jackson seems to take the loftiest place in this story just like Harry Potter took in series of books written by JK Rowling. Anyways, it's a great book for children and grownups alike, but there will be a need to brush up slightly on Greek Mythology to fully understand this bit.
