Solace

Voldemort knows the youngest Malfoy will fail his assigned task to kill Albus Dumbledore, but he has a contingency plan- Moira Macrae, 32 year old pureblood daughter to two of his most loyal followers, suddenly finds herself a Death Eater shipped to Hogwarts, and Severus Snape suddenly finds himself saddled with yet another annoying blonde to keep alive.
