Mystical Paths

I just finished the fifth in Susan Howatch's Church of England series. I love these books! I have never read anything that showed real people grappling with real theological issues as they live out their real lives (and okay, there's a touch of supernatural thrown in, and this last one turns into a bit of a whodunit as well--it's got it all!). I thought this was the last one, but to my delight I discovered there is one more to wrap up the series. The addict's reprieve. Now I must decide whether to get it out of the library TODAY-- NOW-- or to try to wait a month and save it for my vacation in the beginning of June. Of course, on vacation it's easier to read books that are less delectable, and needed for desperate escape from horrible life.

So my question, dear readers, is what next? Is there anything out there comparable to this series?
