[Featured on EqD and FiM Fiction] It is that time again, the dreaded flu season. Not even Princess Celestia, the ruler of the sun and day, is safe from it. When Celestia contracts the flu, what pony could possibly nurse Celestia back to health? Why none other than her dear, loving sister of course! Enter Nurse Luna!

Between crazed guards, a palace staff desperate to please their rulers, and a crazed unicorn running around, no pony is safe from this madness.
