Harry Potter and The Bound Prince

In HBP, there is a pivotal moment where things could have gone very differently for Harry and Draco. In the bathroom sixth year, Draco is upset that Harry has caught him crying and throws a hex. It escalates and ends in blood, with Harry nearly killing Draco by accident. In this story, instead, unvoiced attraction to Harry motivates Draco to take a chance and kiss him. Once sparked, their mutual desire and exploration becomes the driving force in the alternative ending to the series. Draco's "mission" from Voldemort turns out to be more complex than that presented in canon and their solution even more difficult.
