Lifeless Souls (Short Story!)

Lifeless souls wander in the world with no purpose, with no happiness... with no love. They long for life. And so the only way to gain life, is to steal a soul that is alive and vulnerable. To steal the soul you must first bind yourself to that soul, in a way that can never be broken, so before binding you must be utterly convinced that the soul is weak enough to be taken. Star feels that Serena's soul is almost ready for the taking, she has so much trust she has already bound herself. But is Serena really as weak as Star thinks she is?
