For fans of The Wild Robot and Rebecca Stead, a middle grade novel that explores what makes us human—and what it means to be irreplaceable.

Summer 2.0 is not here to replace Summer Dillon.

As an android, she’s a little different: a control panel instead of a brain, a mechanical heart instead of a physical one. She can't quite replicate Summer’s airy laughter, and she can only construct her personality with 93% accuracy.

But Summer 2.0 loves being alive. She loves living with Summer's family, trying new flavors of ice cream, and going to school—just like the real Summer would have.

Summer 2.0 knows she is not here to replace Summer Dillon. She is here to continue her. And as long as Summer 2.0 does just that—remains the perfect Summer—she’ll be able to stay.

But her efforts seem to lead her further and further away from perfection, and a new question arises: if she isn’t the real Summer, who is she meant to be?

From Sarah Everett, the critically acclaimed author of The Probability of Everything and The Shape of Lost Things.
