He had woken up with the kind of energy that made him want to run a marathon. He'd decided on impulse to build a treehouse in the backyard. Liam hummed as he measured the wood, his movements quick and decisive. He imagined the laughter of his future kids, the feeling of the sun on their faces. It felt so good to finally be settled, putting down roots.

The letter arrived mid-afternoon. A curt legal notice. The house had a history, one the previous owners had failed to disclose. Years ago, it held a tragedy, a crime of violence. Liam’s hands stilled, the hammer falling from his grip. The treehouse no longer seemed appealing. His stomach plummeted, the sunshine suddenly felt harsh on his skin.
