The May Bride by Suzannah Dunn (historical fiction 2014)

Pretty good stuff about Jane Seymour's late teens.  Dunn takes on a story with thin evidence and turns it into a believable narrative.

Rubicon - The Last Years of the Roman Republic by Tom Holland (nonfiction 2003)

I enjoyed this book - I've always loved reading about Julius Caesar and Augustus, and it had something new (to me) to offer.  His analysis of the Roman "mindset" of the times is fascinating.

Funeral Games by Mary Renault (historical fiction 1981)

It's about what happened among Alexander's generals and relatives once he died.  It's so good, go get it.  The details are lovely.
