AfterSublimation, the immigrant story will never be the same. Junot Daz, Pulitzer Prize-winning author ofThe Brief Wondrous Life of Oscar Wao

The border cuts you in two.

When you immigrate, you leave a copy of yourself behind. One person enters their new country, the other stays trapped at home.

Some instances keep in touch, call each other daily, keep their lives and minds in sync in the hopes of reintegrating and resuming a life as one person. Others, like Soyoung Rose Kang, leave home at ten years old and never speak to their other selves again. Rose, in America, never imagined going back to Korea until her grandfather died and her Korean instance called her home for the funeral.

She doesnt know that Soyoung plans to steal her body and her life.

How far wouldyougo to live the choice you didnt make?
