The Monster Keeps Me Safe by Kitty Thomas

I didn’t know I was a captive. How could I? I didn’t have my memory. He could have told me anything about the world, and he did.
And I believed him.
Until the day a mysterious stranger showed up, killed the man I’d believed was my husband, and decided to take me with him.
I don’t know what he plans to do with me, but it can’t be anything good.
But at least the world still exists.
