Riordan absolutely loves making allusions to ancient mythology. In the Lightning Thief for example, when fighting Medusa, Percy avoids looking at her by using a garden sphere. This is an allusion to the myths, when Perseus avoided looking at Medusa by using his own shield like a mirror. That's a simple example. Let me know if you need more.
We don't know exactly where the story of Hatchet takes place because Brian is very, very lost. Here's what we do know: Brian's plane comes down somewhere in the North Woods, a vast area that covers much of central Canada<span>.</span>
What is the thesis/main idea of the leader in the mirror?
I️ believe the word ‘sadistic’ would be the poor word choice in this sentence.
Some words I’d suggest would be, “Spirited, sprightly, frisky, combative, quarrelsome,”
Hope this helps and good luck :)
