No. 8: Charlie Thorne and the Last Equation by Stuart Gibbs. A bit Alex Rider, a bit genius not quite philanthropist (without a metal suit) - The math equations were beyond me, and it dragged a little towards the end, but overall an enjoyable, fast paced espionage adventure.
I is for Iorek Byrinson, king of the ice bears in The Golden Compass by Phillip Pullman. The movie version had great casting, but it got lots of things wrong, adaptation wise. (I'm looking at you, ending that was in the trailer, but not in the movie...) The ice bears armor is described in the book as rust red sheets of metal. I think an ice bear would care more about function than form or ornamentation.
I'm an aspiring author / illustrator.
