He is chained to her through his own choice.
She is chained to him through no choice of her own.
A thick chain linking the two of them together by their ankles and kept in place with heavy-duty locks.
She knows why she is there. He has explained that once - and only once. Each subsequent time she asks, he simply tells her that she knows the reason. She knows there is no way out until he says so.
For a time of his choosing, she is his prisoner and that is all there is to it. Yet - for the two of them - things could have been so, so different.
*DO NOT READ BEFORE YOU READ THE ISLAND*
Chained by Matt Shaw is not so much horror, as simply a revenge story. There isn't much action, and far too many thoughts and feelings. Shaw could have easily written this as flash fiction, in order to reach the ending sooner. The final scene caught me by surprise.
I felt a great deal of sympathy for the narrator. Not sure if Shaw is attempting to make a statement with this story, but sometimes fiction can be an eye-opener. I hope readers realize how much damage lying can do to someone's life.
