(Book)

"A novel of the twelve houses"--Jacket.

After joining an unlikely band of soldiers and sorcerers to rescue the kidnapped regent Romar Brendan, the shiftling Kirra returns home to learn that her half-sister, Casserah, has been proclaimed heir to the land. But when Casserah refuses to go on a social tour of great Houses, Kirra shifts into her sister's form and makes the rounds -- during which she unexpectedly meets up with her compatriots from her previous adventures. The motley group faces many dangers -- and Kirra places herself in peril when she falls in love with the married Lord Romar. Revealing her true identity to him, Kirra begins a tempestuous affair that places them both in mortal danger, and leads them both into the stronghold of the devious lords of the Thirteenth House.
