The Princess & the Thief

Ket is a thief, mistress of disguise and con artist. Katrina is a princess on her way to get married to a man she hates. Although their lives couldn't be more different, their faces are alike enough that they could be mistaken for twins.

When their paths collide, Ket takes advantage of their physical similarities and assumes Katrina's identity. The plan is to infiltrate the palace of Oblyan, land herself in the good graces of the royal family, convince them to pardon her uncle, who has been sentenced to death for conspiring against the crown, and get the hell out.

However, nothing is ever that simple.

Soon Ket finds herself cut off from her friends and allies, backed into a corner by Katrina's suspicious relatives and wrapped up in more conspiracies than you can shake a stick at. To make matters worse, she discovers herself engaged to the charming but dangerous prince Aklos, who doesn't quite understand how his fiancée went from a soulless demon to a girl he nearly likes, but isn't above taking advantage.

Ket resigns herself to putting up with Aklos for as long as the charade lasts. However, as time drags by, she begins to grow unsure of her own feelings for him - even knowing that there can be no future for a relationship built on deceit.

(Very, VERY loosely based on Mark Twain's The Prince and the Pauper.)
