The Sea of Monsters: A Reader’s Guide

Percy Jackson and the Olympians, Book Two

About the book:

Percy Jackson’s seventh-grade year has been surprisingly quiet. Not a single monster has set food on his New York prep-school campus. But when an innocent game of dodgeball among Percy and his classmates turns into a death match against an ugly gang of cannibal giants, things get … well, ugly. And the unexpected arrival of Percy’s friend Annabeth brings more bad news: the magical borders that protect Camp Half-Blood have been poisoned by a mysterious enemy, and unless a cure is found, the only safe haven for demigods will be destroyed.

In this fresh, funny, and action-packed follow-up to The Lightning Thief, Percy and his friends must journey into the Sea of Monsters to save their camp. But first, Percy will discover a stunning new secret about his family- one that makes him wonder whether being claimed as Poseidon’s son is an honor or a curse.

Author Interview:

1. What was your process for writing the 2nd book? Did it differ greatly from your first book, The Lightning Thief?

Actually the process for The Sea of Monsters was almost identical. Once I formulated the general idea, I told Sea of Monsters to my son as a bedtime story, just as I had for The Lightning Thief. I made up most of the details as I went along, pulling ideas from Greek mythology. My son loved it and didn’t want the story the end, so I figured I was on the right track. Then I spent about a year writing and revising the novel. When I was done, I read it to my son and also let a few of my former middle school students pass judgment on the manuscript. It’s very important for me that kids like the story, first and foremost. After all, I’m writing for them.

2. Why do you think the Greek myths have endured the ages? When did you first become fascinated with them?

I’ve loved Greek mythology for as long as I can remember. What’s not to like? Brave but tragic heroes. All-powerful gods. Outrageous personalities. Scary monsters. Magic. Love. Fighting. The myths have it all! I think mythology has endured so long because these old stories describe something timeless. Hearing the exploits of the gods and heroes, we learn a lot about the best and worst of human nature.

3. Your hero, Percy Jackson, must straddle two worlds, the human and the mythical. Why did you decide to make him half-human?

All the old heroes of Greek mythology were half-human and half-god: Heracles, Perseus, Theseus. That idea has always fascinated me, because the heroes never completely belonged in either world. That made them more sympathetic to me. I also think all middle school kids feel that from time to time – caught between childhood and adulthood, not really comfortable in either place. Maybe that’s why middle school kids find it easy to relate to Percy.

4. What’s the best part about writing for kids? Do you miss being in the classroom?

Writing for kids has made me a better writer in general. Kids have little patience for extraneous information, so I’ve learned to tell a tighter story. They expect humor, action, good characters, interesting settings – all of which makes for a good novel. When I write the Percy Jackson books, I imagine that I am reading them in front of my class. That helps me to keep the pace fast and the interest level high. I want my readers to love reading, not feel bored! I do miss having my own classroom, but I still visit schools as an author all the time, so in a way I can reach more students now than I ever did as a classroom teacher.

5. What authors and stories have most influenced your work?

Obviously I love mythology and folklore! Aside from that, the first thing I remember reading for pleasure was The Lord of Rings. I was a big fantasy fan in middle school and high school. I loved The Earthsea Trilogy, The Phantom Tollbooth, and the work of Roald Dahl. I still read a lot of great young adult fantasy, everything from J.K. Rowling to Phillip Pullman to Eoin Colfer.

Language Arts:

Visualizing: While reading a chapter highlight (or use sticky note flags) words or phrases that really helped you get a picture in your mind of what was happening in the story. In at least two places create predictions of what you think might happen on later in the story based on what you just read.


Create a 3D scene from the story. You can use any materials you like but try to get as many details from the scene incorporated into your art.


Choose classical music that would work as a background to a particular battle scene in the story. In a short journal explain why you picked this piece.

Social Studies:

Create a chart which organizes the following information: character’s name, child of whom, special powers, tools of choice, goal, and affiliation (Kronos or Olympus).
