This year many great books have come my way, but of all of them I think Chesterton's "Orthodoxy" is the most challenging, and the most enjoyable. It's sort of like good beef jerky: the more I munch, the better the book tastes.
Chesterton lived on the bridge between the 19th and 20th centuries, and reacts against the mess his contemporaries (evolutionists and romantics) have made of the world. It's not that they have visibly torched culture, he argues, but they have made everything "small." Materialists shrink the cosmos because they deny the supernatural and the meaning it brings, and idealists deny the material and so sever themselves from the goodness of creation.
He says it much better than I can, so take up and read it for yourself!
