As of my knowledge cutoff date in March 2023, there is little publicly available information about an author named Alex Wheeler beyond their work on the "Star Wars: Rebel Force" series. Alex Wheeler is a pen name used by an unknown author who contributed to the "Star Wars: Rebel Force" series, a collection of young adult novels set in the "Star Wars" universe, which follows the adventures of Luke Skywalker, Leia Organa, and Han Solo. The series fits into the larger "Star Wars" Expanded Universe, now rebranded as "Star Wars Legends" after Disney's acquisition of Lucasfilm and the subsequent reorganization of the canonical continuity. If there have been updates or new information about Alex Wheeler after March 2023, I would not have access to it and recommend checking current sources for the latest details.
