Has anybody read "The Vintner's Luck" by Elizabeth Knox?

I'm a huge fan of the Belgian actor Jérémie Renier (L'Enfant, A Love to Hide) and a few weeks ago I was looking at his IMDb page and saw that he had signed up for a movie called The Vintner's Luck based on a novel by the New Zealand author Elizabeth Knox; further research revealed that Niki Caro (Whale Rider, North Country) was set to direct, with Gaspard Ulliel (A Very Long Engagement, Hannibal Rising) and Vera Farmiga (The Departed) on the co-star list--unfortunately, it looks like financing fell through at the last minute, so it's been delayed until next year.

Anyway, the reason I mention it here is because according to blurbs about the book it seems to have a homoerotic aspect -- the novel covers 55 years in the life of a French vintner (the role that was to be played by Renier) who, one day early in the 19th century, finds an angel (the Gaspard Ulliel role) in his vineyard, and they met every year thereafter, even, apparently becoming lovers at one point!  I wonder if anyone has read this novel?  Sadly, it appears to be out of print here in the U.S., but I'm scouring used bookstores to see if I can find it.  Would love to hear from anybody who may have read the book.
