" I tortured myself day after day with what if? questions. What if I’d been faster and stronger during the Strigoi fight? What if I hadn’t told him where the Strigoi were in the first place? And what if I’d simply been able to return his love? Any of those could have kept him alive, but none of them had happened. And it was all my fault. "
