Winner of the Carnegie Medal * Winner of the YA Book Prize * Winner of the Children's Books Ireland Book of the Year Award

Tippi and Grace share everything--clothes, friends . . . even their body. Writing in free verse, Sarah Crossan tells the sensitive and moving story of conjoined twin sisters, which will find fans in readers of Gayle Forman, Jodi Picoult, and Jandy Nelson.

Tippi and Grace. Grace and Tippi. For them, it's normal to step into the same skirt. To hook their arms around each other for balance. To fall asleep listening to the other breathing. To share. And to keep some things private. Each of the sixteen-year-old girls has her own head, heart, and two arms, but at the belly, they join. And they are happy, never wanting to risk the dangerous separation surgery.

But the girls' body is beginning to fight against them. And Grace doesn't want to admit it. Not even to Tippi. How long can they hide from the truth--how long before they must face the most impossible choice of their lives?

Carnegie Medal-winning author Sarah Crossan gives us a story about unbreakable bonds, hope, loss, and the lengths we will go to for the person we love most.
