A Tale of Two Sisters

Neither of the twin princesses, Monserrat and Sheva, expected to ascend to the throne of Dorn. Their father sat on it and after him came their older brother, but when tragedy strikes and Sheva finds herself first in line, she also finds she's not ready.

When the stress becomes too much on a royal tour of the other nine nations of Temmeland, Sheva's husband suggests the twins change places temporarily. They've done this before, innocently and just for fun when they were kids, but can they carry it off now, as adults in public? And what will become of this odd arrangement if Sheva decides she prefers it?

More worrying: what happens when the leading light of a rival family of nobles, The Lady Jane Pomeroy discovers the deception?
