Fantasy books aimed at pre-teen children can be a bit formulaic. Usually a child, just before puberty, when they are feeling like they should be capable but feel powerless, is sent into a magical realm where they expect to be powerless but end up saving the world. Sarah Prineas
Winterling (2012) is such a work. What was interesting to me about it was the way that the basic situation was that of the Hittite king Ammunas. The story takes this basic situation and tries to work out a solution. I doubt that Prineas has ever heard of Ammunas, but it was interesting anyway.
