It is! I had the basic outline fairly quickly and it was just writing it up, but the ending wasn't clear. I really didn't want Harriet and Peter to have to meet up again, given the story was largely complete once he came up with a solution to the problem. But it sorted itself out in the end.

The equinox is driving me nuts! All I ask is steady nighttime temperature and for it to get light at 4 or 6.30, but not in-between.
