Mark Blackthorn's heart and mind are battling against each other- constantly. His mind wants to forget the prince of the Unseelie Court but his heart wants to remember Kieran forever. They say follow your heart, but when you are a Shadowhunter, ruled by the Clave and its motto: 'the law is hard, but it is the law', when your own sister was exiled due to her Downwolder blood which is no other than faerie blood and when your family is in danger of being destroyed, due to the secrets your younger brother keeps- What should you follow? Caution: Lady Midnight Spoilers & Yaoi. It's my first fanfic, so feedback is more than welcomed. The majority of the characters and places belong to the amazing Cassandra Clare, who created the world of the Shadowhunters.
