Son of Sobek

The Son of Sobek is a short story(about 40 pages) by Rick Riordan. The point of this was to get readers more interested by combining Percy Jackson and Carter Kane. The book is very interesting, as it combines, Carter's power's (like combat avatars), and Percy's powers. Carter and Percy fight together to save a bunch of mortals in Long Island

This Greek-Egyptian mix was very good but could have been a little better if Rick Riordan had actually got Percy and Carter to talk more about who they are, and to try to explain themselves to each other. Another problem is that the author never mentions when this book takes place, (in relation to the Kane Chronicles, Heroes of Olympus, and Percy Jackson and the Olympians books). I can't blame him though, as this was a side project to the House of Hades.

Heroes of Olympus series

The Heroes of Olympus is a series written by Rick Riordan. This series is connected to the Percy Jackson series, and once again takes place partially in Camp Half-Blood. This time, there are many new characters. Also, the series introduces you to Camp Jupiter, the Roman demigod camp in California.
So far there are 4 books in the series, (The Lost Hero, The Son of Neptune, The Mark of Athena, and The House of Hades). Book 5 (Blood of Olympus) is to be released in 2015.

In the Percy Jackson series, the antagonists are the Titans (mainly Kronos), whereas in this series, they are Gaea and her children (the giants). The driving force of this series is the Great Prophecy shown below:

Seven half-bloods shall answer the call.
To storm or fire, the world must fall
An oath to keep with a  final breath,
And foes bear arms to the doors of death

In the Percy Jackson series, the antagonists are the Titans (mainly Kronos), whereas in this series, they are Gaia and her children (the giants). Throughout the series, the demigods work together in both camps to stop the giants, and in the 3rd and 4th books, seven demigods, Greek and Roman go all the way to Greece and Rome in order to close the doors of death, and defeat Gaea.

These books display many important virtues such as friendship, loyalty, bravery/courage, etc. Like the Percy Jackson Series, this series also teaches you lots of Greek Mythology, as well as Roman Mythology. So far this is a very good series which is most certainly worth a read.

Ratings: An average of 7+ for the series. The 2nd and 4th are better than the others in my opinion.
