One title on the list:
The Gate of Angels by Penelope FitzgeraldRead about the other angels on the list.
Fred Fairly is a scientist, an academic at St Angelicus ("Angel's") College, who can't help thinking of angels. "Fairly perhaps sees a bird flying over the fens, and he looks attentively at a young woman, and he combines the two of them, and imagines an angel. That is how the imagination works." He falls in love with Daisy, who is a kind of angel (a nurse, anyway).
