Bound and Determined

After the events of DH, Harry should be happy. Instead, thorough a hasty vow, he is stuck in a forced, three-way bond, and he is NOT pleased. So he decides to fight back, the only way he knows how: to get more Slytherin than the Slytherins. A rather dark fic (though with a happy ending in the wings.) Warnings: Bashing of Lucius Malfoy, living Snape, non-explicit non-con, and mpreg.
