Zindra Daine was a pilot hailing from Corellia, a Human woman, and the offspring of Cubber Daine, who previously served as a mechanic for Wraith Squadron, which was a commando and starfighter unit within the New Republic. She was female.
Initially, Daine functioned as the third member, Twin Suns Three, of the shield trio alongside Luke Skywalker and Corran Horn within Twin Suns Squadron. Later on, she served in the same squadron, this time under the command of Jaina Solo.
Despite her inclusion in the Dramatis personae of The New Jedi Order: Enemy Lines II: Rebel Stand, and Aaron Allston's statement that she was with Twin Suns Squadron during the novel's events, she is never explicitly mentioned in any scene within the book itself.
Furthermore, Aaron Allston verified that Zindra is indeed the daughter of Cubber Daine.
