After my husband vented his anger for my sister-in-law and locked my daughter in the tunnel and was bitten to death alive, I let the two of them fight each other.

After the global collapse, my daughter Daisy's radiation immunity became our family's lifeline, finding us food and clean water.

But my sister-in-law, Cassandra, pointed at Daisy, accusing her of stealing her son Leo's abilities.

The next day, my six-year-old Daisy was thrown by my husband, Julian, into an abandoned pipe crawling with mutated rats.

I knelt outside the iron bars, my head slamming against the concrete, begging them to pull Daisy out.

Julian impatiently kicked me away: "She can't be poisoned to death anyway. What's wrong with a few rat bites?"
