There are lots of books about schools for magical kids: Hogwarts, Camp Half-Blood, Unseen University, Strange Academy, and on and on.

But what about a retirement home for magical grownups? Imagine reaching a ripe old age, children and grandchildren grown and gone, and one day you find a gold-embossed letter in your mailbox:

"Greetings!
You have been selected for residence at the Moonfrost Home for Exceptional Elders."

Somebody write a novel about a magical retirement home. I want to read it.
