I enjoyed Lafayette by Harlow Giles Unger so much I stopped reading it for a couple weeks when I noticed I was almost through it. Did not want it to end.
Alison Weir is one of my favorite authors; two of her best (I think) are Queen Isabella (what a fuckin story) and The Lost Tudor Princess, which sounds vague and flighty but is like a high-beam flashlight into the time period.
Back off, Warchild. Seriously.
