Help with a location?

OK, so I am in the process of writing the outline for an eight book modern fantasy series. It's about a boy who lives in Seattle with his elderly foster mother and is one day attacked by a horrendous creature. Someone --who turns out to be his uncle-- saves him from the creature and brings him back to his house, unconscious and in shock. He explains to him that he belongs in another world, where his parents were from. His parents, who died after being wrongfully exiled by and evil man. This world is a world of magical creatures and powers, where things are powered off of magical energy rather than electricity.

My real question is, where should this world-- or at least the part of this world that is in the USA-- be?

A. The Olympic National Park on the Olympic Peninsula in Washington which is one large mountain surrounded by foothills and forest

B. All along the Washingtonian section of the Cascade Mountains that run through the middle of the state, north to south with many mountains and forests.



A's Pros and Cons...

Pros, it is more isolated as it makes up most of a peninsula, so really only one side of it would be even open to 'our world.' It is more of a square shape which would make travel and everything easier. It also has only one road running through it.



Cons, It's three times smaller than the Cascade range as its about 30 miles wide and 40 miles long



B's Pros and Cons...

Pros, It is alot bigger, almost 200 miles long and has lots of mountains rather than one



Cons, It is only between 8- 30 miles wide and has 'our world' on two sides. It also has alot of highways and roads through it.Help with a location?
I would go with Olympic National Park.



A single mountain is always more mysterious and fascinating than a mountain range.



I would make a connection to the Greek gods of the ancient myth of Mount Olympus. Maybe those Greek gods relocated to the State of Washington. Make a connection with George Washington, the State of Washington, and the secret Masonic Order that George Washington was a leader in.



I assume the mountain in Olympic National Park is an extinct volcano. I'd use that fact too in the story.



I would fudge the dates a bit and claim that the modern Olympic Games began at the same time that the State of Washington joined the United States.
I would say A cause then this guys uncle can talk about how close they are to exposure and how they have so little place to live and might have to blend in with humans which probably wouldn't work and other stuff like that...

Hope I helped!!!Help with a location?
The first one seems more.. I don't know. Like..I can FEEL it. If that makes sense. It seems cozy, isolated, and has the right mood to it. It also reminds me of Twilight..but we can just overlook that:)



The second one sounds like it would be shaped like the country Chile. And I'm more of a Europe person, not Spanish. Well anyway...



good luck with your books!
