Alexis has a secret about her-...er, himself. Well, it's not really a secret-at least not outwardly-but it hasn't been expressedaloud to anyone else, except the therapist. He hasn't told anyone yet, but plans on telling Sof a first, mostlybecause she lives thousands of miles away in Buenos Aires. Alexis and Sof a have been pen pals since the 6th grade, and since they have never actually met IRL (in real life), Alexis feels more comfortable telling her first.Sof a, too, has just learned of a secret that her parents have been keeping from her, one that upends her life and changesthe way she thinks about everything. In a letter that Sof a inadvertently finds in her father's desk drawer, she learnsthat her abuelos-her mother's parents-are not only not her real grandparents, but who they are and, more importantly, who they were, are in direct conflict with who Sof a is and what she believes. While Alexis struggles with identity, so too does Sof a. In this story, two virtual friends work together to solve their ownmysteries, one intensely personal and the other about how she now relates to her own family as the secrets of thepast-the family's and the country's-become even more real.
