Thank you!
Four For a Boy is from the rhyme about magpies. It seemed apropos, since the original rhyme ran three for a funeral and four for a birth, and of course the birth of little William makes the Hamilton-McGraw family four instead of three, and changes Thomas’ death.
To the Upper Air comes from the quote from Virgil’s Aeneid, and the minute I read the quote I knew I had to use it as a title for the story I was writing, because of course the theme of the story is the struggle to come back to life and to themselves after the hell that James and Miranda have been living for the past ten years and that Silver has been dealing with for the past fifteen or twenty. Also, they’re quite literally coming back from another time, in Miranda’s case quite literally after having died.
