Ask HN - Recommend some current business/entrepreneur books

I'll doing a bit of traveling in central america over the next few months and i'm going to have some downtime. I like to use times like these to squeeze in a lot of reading and was looking for a few current/new books on business, marketing, etc.

I'm pretty up to speed w/ all the "classics" - art of war, tipping point, the long tail, seth godin, and a lot of the material on josh kauffman's personal mba list but i was wondering if there was anything new and noteworthy that the community would like to share.
