Just awesome.
Some holiday anthologies fall short, probably because a short story is just darned hard to write. But not this one. In the first place, these stories aren't all that short. This has allowed each of the three authors to write a well imagined romance with enough mass to be moving. I particularly loved Mary Ann Rivers's Snowfall. (I love nerdy heroes. Love. Can't help it.)
Read it. You will not be disappointed.
