Enhanced descriptions from Syndetics:

Award-winning author Justina Chen delivers a powerful and heartfelt novel about a young girl who accidentally discovers she has an identical twin sister. This uplifting novel about reunited adoptee sisters experiencing new family traditions, foods, and customs together is perfect for fans of Janae Marks, Kelly Yang, and Meg Medina. Dive into a nuanced portrayal of the transracial, transnational adoptee experience, including the joys and the sorrows within the wide spectrum of experiences as an adoptee.

On Dessie Mei Breedlove's first day at a new school in the middle of her sixth-grade year, who does she see? A classmate who looks exactly like her. As in: Dessie and Donna Lee have the exact same glossy black hair. The exact same brown eyes. The exact same cheeky smile.

A secret DNA test reveals the shocking truth: Dessie and Donna are identical twins, adopted from the same orphanage in China, then separated into two different families: one white, the other Taiwanese American. The Breedloves and the Lees.

Making up for lost time, the girls throw themselves into their newfound sisterhood, relishing every similarity. Cats or dogs (dogs!). Sweet or savory (both!). Favorite band (A2Z, duh!). But the small differences between the girls soon create tension...and when crisis strikes, Dessie must figure out who she is, where she belongs, and what it truly means to be a sister.
