Domnall, an old, cranky, and insufficiently respected Fae scout, is sent on a mission to find a human home with a young baby and a nursing mother. Maeve's daughter is sick and not recovering, and needs the human magic of mother's milk or she may die. He finds a suitable nursing mother, and does the switch, and all is going to be well.
Until he discovers that the humans are planning a baptism in just a few days' time. He manages to do the switch again, but in the process the Fae child is injured, and sicker than ever.
And the Fae child still needs human mother's milk, and they'll have to go even further afield to find one in a place where the humans won't be on high alert because of this incident. So Domnall comes up with an even more dangerous plan.
Old, cranky Domnall won't give up, and, purely out of necessity, keeps coming up with ideas that are Just Not Done, especially in a community of Fae that has grown few in number, and very cautious. In the process, Domnall grows, some of those around him grow, and maybe there's a breakthrough with some unfriendly neighbors.
And maybe Domnall isn't quite as past it as he thinks.
It's an interesting and charming tale. Recommended.
