Eva and Addie started out the same way as everyone else—two souls woven together in one body, taking turns controlling their movements as they learned how to walk, how to sing, how to dance. But as they grew, so did the worried whispers. Why aren’t they settling? Why isn’t one of them fading? The doctors ran tests, the neighbors shied away, and their parents begged for more time. Finally Addie was pronounced healthy and Eva was declared gone. Except, she wasn’t . . .
For the past three years, Eva has clung to the remnants of her life. Only Addie knows she’s still there, trapped inside their body. Then one day, they discover there may be a way for Eva to move again. The risks are unimaginable-hybrids are considered a threat to society, so if they are caught, Addie and Eva will be locked away with the others. And yet . . . for a chance to smile, to twirl, to speak, Eva will do anything.
This is an intriguing idea, though I was not convinced from reviews I’d read that this would be a novel I’d find satisfying.
Initially I found the novel quite confusing. As a number of readers have commented, there’s a lack of detail to help explain why this world is as it is. However, there are some details given later on, and it’s strongly suggested that more answers will be given in part two of the series. On balance, this lack of detail doesn’t interfere with enjoyment of the story itself.
The creation of two distinct characters is handled well by Zhang. I felt deeply for both girls as they struggle to do something they’ve been brought up to believe is dangerous though it might bring them happiness. It doesn’t ruin the reading experience to know that there are some unscrupulous people who are running experiments on children like Addy, and that a lot of the novel is set in the clinic where these experiments are taking place.
Personally, I felt parts of the novel dragged but the pace picks up towards the end and brings us to a satisfying conclusion.
