Not really, alas! I learned most of this in seminary, and it was focused on specifically Christian history, which Constantine had a huge influence on, but he was never the focus. I'm sure there are good books out there (check your local library), but the texts we read for class would probably not be very good if you wanted to find out more about Constantine himself and the broader historical context, as opposed to, say, the First Council of Nicaea (which he called for and sponsored).

I'd start with the wiki article and look at the citations, see if any of the books seem interesting; or search your library's catalog.
