In fiction, I'm reading the English translation of Arturo Perez-Reverte's The sun over Breda, 3rd in a series of coming of age tales of a young Spanish soldier in the early 17th century. It's a dashing tale, and I recommend the entire Alatriste series for anybody who likes those.
In non-fiction, I just started Robert Kagan's Dangerous Nation, which is an interesting retake on the early history of American foreign policy. Kagan is definitely one of the more serious and greater minds on American foreign policy writing today, and has the added benefit of being a pleasure to read. So far, I'm liking his take on the politics of the Revolution a good bit.
