William's Picks
Percy Jackson and the Lightning Thief by Rick Riordan
This book is about Percy Jackson. He lives with his mom before he knows he has any special powers. When danger comes his mom tries to get him to Camp Half Blood for training but a minotaur attacks.  Percy finds out his dad is a god and he is then accused of stealing Zeus' lightening bolt and has to find it.

This is based on greek mythology and I really liked it. I could not wait to read the next book.
Percy Jackson  and the Sea of Monsters by Rick Riordan
 Percy Jackson is on another adventure: he has to travel through a sea of monsters to get the golden fleece.  

My favourite part was when Percy fought two unique monsters: Scylla and Charybdis. The monster Scylla lived in a cliff and ate passing sailors while Charybdis lived in the ocean and could swallow the sea.

This book was bigger, longer and better than the Lightning Thief. 
Percy Jackson - The Titan's Curse by Rick Riordan

Percy Jackson and his demigod friends have to find the goddess Artemis who has been held captive by the titan Atlas.

My favourite part of the book is when the demigods enter Hephastus' junkyard which is full of monsters.

I liked this book but preferred others in the series.

Percy Jackson - The Battle of the Labyrinth by Rick Riordan

In this book Percy Jackson goes into the Labyrinth.
and meets Daedalus the Inventor. He is trapped by king Midas and has to escape.

My favourite part of this book was when he meets Daedalus.

This was one of the better books in the series.
Percy Jackson and the Last Olympian by Rick Riordan

This is the final book in the series.

Percy Jackson needs to fight his arch-enemy
and the god (actually he's a titan) of time Kronos.

My favourite part was when Percy had to fight Kronos.

This was my favourite book in the series and I really wanted more.
