Who's the Baby's Father?

Reeling from the shock of waking up in labor, a woman realizes that she is in the body of Princess Etricia Lette, the anti-heroine of a novel she never finished. The only thing she recalls is that Etricia had countless suitors, so the father of her baby girl, Loustina, is a mystery, but he could be one of four powerful men. Is it the captain of the imperial knights, the prince of a neighboring country, the master of the mage tower, or a descendant of dragons? Who will Loustina call father?
