More Precious than Rubies (слэш)

Harry Potter has recently escaped from his dragon-guarded tower. So has his fellow prisoner - the dragon who was enchanted to guard him. Harry's friend is missing, however, and so he sets off to assure himself of his well-being before he finds the person responsible for imprisoning them both. Accompanied by a stranger with a familiar name, Harry finds himself with more questions than answers as he slowly learns about the customs of dragons and the history of the dragon he befriended, the fearsome Voldemort.
