The worn sofa cushions molded to Liam’s form as he sunk into them. The afternoon sun cast long shadows across his living room, illuminating the dust motes dancing in the air. He clicked on the link his friend had sent. The article was a tale of his youth, the summer he spent backpacking through Europe. His words, his memories, staring back at him beneath the name "Eleanor Vance." A bitter, hollow feeling filled him.

He felt a sudden ache for simpler times.

His hands clenched.
