Grace and Tippi. Tippi and Grace. Two sisters. Two hearts. Two dreams. Two lives. But one body.

Grace and Tippi are conjoined twins, joined at the waist, defying the odds of survival for sixteen years. They share everything, and they are everything to each other. They would never imagine being apart. For them, that would be the real tragedy.

But something is happening to them. Something they hoped would never happen. 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?

One is a beautiful story about 16-year-old conjoined twins, Grace and Tippi, that really got me to thinking about a way of life completely different to anything I am used to. It is a story that reveals what it means to have a soul mate – albeit not in the traditional sense of the word. The entire novel is written in beautiful, flowing verse that had me in tears and it will remain one of the most poignant stories that I have read this year.

Tippi and Grace have been by each other’s side since birth. They are conjoined from the waist down, and have lived their entire lives sharing every single moment. Having always been home-schooled, they now must attend the local private high school as juniors and face the possibility this brings of staring, disgust, ridicule and judgement.

However, they grow to enjoy normal school life more than they expected, and even make some friends. They smoke, they drink, they go on a road trip – they experience the normal teenage life they have never had the freedom to live before. The normal complications of love, boys, privacy, family drama and angst are discovered through a totally new perspective. When Grace’s health worsens and becomes life-threatening, the twins have to decide whether they wish to be separated for the first time in their lives – the outcome of which will bring a series of devastating physical, emotional and psychological impacts.

I have never read a YA book like this – it was incredibly life-affirming and powerful. I felt that it was extremely clever for Sarah Crossan to write the twin’s tale in verse, because she showed that a story can be deeply moving and hard-hitting, with just a few words. The use of verse also made the novel incredibly easy and free-flowing to read – I finished it in one sitting; in a matter of hours and I found that the words just swept you up completely in their stark, simple poetry. This way of writing created a distinctive and magically profound voice that I feel would have been impossible to replicate with normal prose.

I also found it interesting that the author chose to pen the story through only Grace’s perspective, rather than both the twins. Tippi tended to control all situations and decisions so it was effective to read the story from the shyer and less-dominant twin’s viewpoint.

In summary, Crossan has achieved a powerful, heartfelt, and deeply moving novel that explores the true meaning of the word sisters. The enormous amount of research into conjoined twins was apparent and it read as factually accurate, but also emotionally hard-hitting. It was amazing to read something that perhaps I wouldn’t normally pick up. It is the first time I have read a novel written in verse, and I am glad to say it worked perfectly. I think the writing structure contributed greatly to the meaning and significance of the story. Grace and Tippi’s is an emotionally deep tale that is all at once lovely, shocking and utterly heartbreaking.

One is like nothing I have ever read before, and is a unique and poignant exploration of friendship, sisterhood, strength, soul-mates and love.
