Riordan

Set in the 15th century. This is weird, but bear with me. He is a baron and you were invited to a feast at his castle. You were accused of killing his faithful hound, but did you really, or are the charges false? He is angry and as payment/revenge, he demands that you teplace his hoound and act like one until he finds a satisfactory replacement. Good luck. You can be anything (even a peacock), and either gender is savvy.
