I grew up in a comfortable house with two parents and a white-picket fence. My brother, Sam, and I used to play with sticks in the backyard and pretend they were swords. There were always cookies on the table and milk in the fridge. Then, one day, things changed.

Sam changed.

Life was never the same again. Sam left. My parents abandoned him when he needed them most, and I was left to survive in a house that was merely a shell of what it used to be. Mom cried all the time and Dad expected me to fill the void my brother left behind. But mostly, all we did was pretend. We pretended that things weren’t messed up. We pretended that Sam never existed.

Until I changed, too.

Now, everything’s a mess and I’m so confused. It’s like there are two different people trapped inside one body—my body—and one of them wants out. I do things. Bad things and I don’t know how to stop. I’m not sure I want to. The only way I can be normal again is if I find Sam. He’ll know what to do.
