Cobalt Squadron tells the story of the Resistance's crack bomber pilots and technicians, including sisters Rose and Paige Tico, survivors of a world overrun by the First Order. Encountering another family on the run, the sisters undertake a mission to provide emergency aid to the Alterra system. Outwitting the First Order and helping people in need will take all of their ingenuity, bravery, and teamwork.
Cobalt Squadron overlaps the events of The Force Awakens and establishes the back-story for the Tico sisters. Many readers will find it helps deepen their appreciation for Paige and Rose as we see them on screen in The Last Jedi. In particular, it adds weight to Rose's sense of loss and her deepening sense of resolve through the film.
From New York Times best-selling author Elizabeth Wein (Code Name Verity, Rose Under Fire), this middle-grade novel is all about the pilots and technicians of the Resistance's very own Cobalt Squadron. New characters from The Last Jedi, including mechanic Rose Tico and her gunner sister Paige, get the chance to shine in this hardcover adventure.
