Have started re-reading Livy's The War with Hannibal. It's an extremely sensationalized story to anyone who's actually done research on the Second Punic War, but it's still entertaining.
I've heard it's a good read; I'll put it on my list for this summer.
Meanwhile, I'm on a Timothy Zahn kick now, plowing through Cobra and Blackcollar. Blackcollar is Zahn's earlier work, and it shows- it's a good bit cheesier than, say, the Thrawn Trilogy, but still quite entertaining. Cobra is a lot grittier, it's basically the mature Zahn going beyond Star Wars and writing his own universe. AAMOF, Since the SWEU is kinda shut down ATM, Zahn's evidently working on the 8th Cobra book right now, due sometime 2015.
