I've only ever heard good things about it! Although, writing a novel where it's based in Chicago isn't as easy as it seems, especially when you don't know the surrounding areas, but I'm getting there. And I'm already obsessed, especially since coming across Wacker Drive!
And thank you, I'm an author, so I write novels. :P I have one published and a few coming soon (I hope), feel free to check them out on my blog if you are interested. :)
