Aegis in the Abyss (слэш)

Unbeknownst to Harry, at the moment of Dumbledore's death, the protection bond known as the Aegis latched onto a new protector. Two years later, Voldemort finally has his hands on his human horcrux and has granted Severus the privilege of breaking him. It's the old adage: you can't break what's already broken. But who broke Harry Potter in the first place and is Snape willing to put him back together again...or does he have other ideas? HP/SS
“But, you said it was wise not to trust you,” Harry said.
Severus blinked. “I lied.”
