Christmas book ideas

I've recently read two different graphic novels that I've been very impressed by. I recommend both of them for smart teens and older.

Logicomix, Apostolos Doxiadis and Christos Papadimitriou

The story of Bertrand Russell and his mathematical (and other) passions. An entertaining story with enough of the history of logic to make me think. Beautiful art of Athens too.

Grandville, Bryan Talbot

A well-written steampunk detective story using animals. But it's more than that, lots of references to all sorts of interesting things and people. The art is captivating and left me wanting more of it.
