Thanks, everyone! Love the comments and love the movie suggestions. I'm in the middle of figuring out the story of Feral book 7 and I'm watching a lot of movies. Movies spark so many ideas for me, often in very off-the-wall ways.
I've seen a lot of the movies you've named. I LOVED Inception, Avatar, and The Adjustment Bureau. And, of course, all the Harry Potter and Lord of the Rings movies. The very weirdest I've ever seen, the one Ilona mentioned, was Donnie Darko. At the end, I was shaking my head with a great big, "What the...?"
Lynn, you asked, "How do you know that the Dupont Circle fountain ISN'T an entrance into the Fey world?!?!?" LOL. Have you read my first book, THE DARK GATE? Because, yep, the Dupont Circle fountain is definitely the entrance into the Esri world.
