At this point in my writing "career," I have now finished or nearly finished five different novels. Of all of them, I can honestly say that
Jefferson's Road: The Spirit of Resistance is the one of which I'm most proud. It was certainly the most satisfying to write: exploring these characters and the settings with this incredibly tense question hanging by a thread all the way through it. Seventy-five thousand words or so under a Damocles' sword. Nothing else I've written yet really comes close to that.
That being said, I'm quite proud and satisfied by the other books I've written, whether independently released or professionally published (or soon to be submitted). But this is still my favorite.
