I really wasn't expecting much from this; it sounded like a silly crossover to me. I'm pleased to say I was wrong! This is possibly the best "Harry rescued from the Dursley's and raised by someone else" stories I've ever read. Please do continue!

I'm hoping to eventually incorporate some of the FK themes in here, too. Seems to me that Snape and Nick would understand each other when it comes to things like repentance and forgiveness. Natalie will be showing up eventually, and while Henri/Harry will have more help and support than he did in the original, he won't go whining to Daddy every time something goes wrong, either....
