And their lives are about to change.
No longer able to afford homeschooling, they must venture into the world - a world of stares, sneers and cruelty. Will they find more than that at school? Can they find real friends? And what about love?
But what neither Grace or Tippi realises is that a heart-wrenching decision lies ahead. A decision that could tear them apart. One that will change their lives even more than they ever imagined.
From Carnegie Medal shortlisted author Sarah Crossan, this moving and beautifully crafted novel about identity, sisterhood and love ultimately asks one question: what does it mean to want and have a soulmate?
