Neither of these two are new, but they're both solid...well, if you like the types.
Gödel, Escher, Bach: an Eternal Golden Braid by Douglas R. Hofstadter - I found this very entertaining and provocative, mentally. The Wiki page describes it well:
"Gödel, Escher, Bach: An Eternal Golden Braid (commonly GEB) is a Pulitzer Prize-winning book by Douglas Hofstadter, described by the author as "a metaphorical fugue on minds and machines in the spirit of Lewis Carroll".
On its surface, GEB examines logician Kurt Gödel, artist M. C. Escher and composer Johann Sebastian Bach, discussing common themes in their work and lives. At a deeper level, the book is a detailed and subtle exposition of concepts fundamental to mathematics, symmetry, and intelligence.
Through illustration and analysis, the book discusses how self-reference and formal rules allow systems to acquire meaning despite being made of "meaningless" elements. It also discusses what it means to communicate, how knowledge can be represented and stored, the methods and limitations of symbolic representation, and even the fundamental notion of "meaning" itself.
In response to confusion over the book's theme, Hofstadter has emphasized that GEB is not about mathematics, art, and music but rather about how cognition and thinking emerge from well-hidden neurological mechanisms. In the book, he presents an analogy about how the individual neurons of the brain coordinate to create a unified sense of a coherent mind by comparing it to the social organization displayed in a colony of ants."
The Great Game - The Struggle for Empire in Central Asia by Peter Hopkirk - fascinating historical account of the first go-round of the West's attempt(s) to subjugate this region of the globe. Analogous to great mountaineering epics in the many stories of men enduring the nearly unimaginable in pain and endurance combined with the requisite subterfuge whenever two countries (here, England and Russia) vie for dominion over new territory.
The Khanates are still operating, centuries later, the way Ghengis installed them - never before contacted or witnessed by Westerners. After reading this, it was easy to see why Kipling placed his "Kafiristan" in The Man Who Would Be King in remote northern Afghanistan.
Of course, it includes a detailed account of the infamous British retreat from Kabul to India. Nearly 20,000 British and Hindu troops (and support staff) of the British Army started the retreat. Only ONE man made returned alive over the Khyber Pass to India. Presumably, he was allowed to live that he might give the British in India his account.
