Collateral - The Nameless Wanderer, #2

Everybody said my sister killed herself. I refused to believe it. I talked to her three roommates. Within 48 hours, one was dead, another ended up in hospital, and the third disappeared from campus. And I was beat up, stomped on, and tossed out. This only made me more determined: someone had gone to extraordinary lengths to silence anyone who could shed light on my sister's death. But as I peeled back the layers of mystery surrounding her death, I was no longer so sure I wanted to know the truth.
What if she was really an escort, like her roommates said?What if she had sold her body for money, or worse, had tried to drag other girls down with her?
