Jake Tapper's Charlie and Margaret Marder series - The Hellfire Club and The Devil May Dance. Loved them; I rarely take the time to write reviews on Goodreads but I did for these two.

I just bookmarked your article in my Archive list because I am always trying to find ways to persuade my daughter to love reading books including fiction. It's like torture for her, which makes me as a huge bookworm feel very sad :'(
