Such an apt description.
Ah, definately can't disagree with that!
I've read the first three of Iguldden's books, and I liked them. The fourth is sat on my bookshelf waiting its turn. They are definately not bound tightly with history, but hey...they're novels. They're fun. And they can help you while away a five hour train journey.
They're worth a read IMO, but don't expect too much. The bit that really irritated me was the way that Brutus and Caesar grew up together...what?!? Now come on, I've read some random things in my time, but...heck! A whole new level of weird idea.
