Sword of the Guardian
"Princess Shasta is a spoiled young teen who's got everything: royal blood, beauty, wealth, power, and influence. But her life is turned upside down when her dashing twin brother? heir to the kingdom? is murdered at a party in front of the royalty, nobles, and others. If not for the quick intercession of Talon, a young acrobat performing at the party, Shasta would have been stabbed, too. The king decrees that Talon be Shasta's bodyguard, not realizing that 'he' is actually a she. What follows is a terrific adventure, coming of age story, a romance, and tale of courtly intrigue, attempted assassination, and gender confusion as the young princess learns, grows, and comes into her own."--Publishers description.
