Once upon a time, in an alternative universe, Han Solo and Princess Leia had three children, unlike the new “official” universe timeline, in which they had only one son, Ben Solo, who would grow up to be Kylo Ren and (spoiler alert!) kill his own father. In this new “official” universe, the Empire has transmogrified into something called the First Order. The Rebel Alliance eventually became the New Republic, but there is also a group called the Resistence. (This part gets confusing.) Leia is now a general instead of a princess, C3PO has a red arm, and R2D2 is in sleep mode. Oh, and Luke Skywalker has been missing for years. (See "Star Wars Episode VII: The Force Awakens")
In the alternative universe (now called the “old canon”, or “legends”), a lot of other stuff happened. (More spoilers!) Luke Skywalker set up a Jedi Academy on Yavin 4, an extragalactic warrior race called the Yuuzhan Vong spread across the galaxy like a vicious plague, Chewbacca was killed, Han became an alcoholic, Luke married an Imperial assassin, Mara Jade (originally sent to kill him, she instead fell in love with him because, well, Luke...), and they had a son named Ben Skywalker. There was also a rogue planet that was alive, and there were these weird things called dovin basals. (I still don’t know what they hell they are.)
Back in the ‘90s, following the success of Timothy Zahn’s Thrawn trilogy, numerous authors joined in on what is now called the Star Wars Expanded Universe (SWEU). The film series officially ended with “Return of the Jedi”, and it would be another decade before George Lucas would make his prequel trilogy.
In that long “meantime”, hundreds of novels, comic books, and short stories were published within the official SWEU, not including the unofficial fan fiction in countless fanzines.
In 1995, Kevin J. Anderson and Rebecca Moesta started a young adult book series featuring the young children of Han and Leia. Twins Jacen and Jaina Solo were training to be Jedi Knights by their Uncle Luke on Yavin 4, along with children from all over the galaxy who had promising Force abilities. These children were recruited by Luke to hone their abilities in a school-like setting where they faced strange and interesting tests and adventures.
Strangely enough, the Young Jedi Knights series predates J.K. Rowling’s Harry Potter series by three years. “Harry Potter and the Sorcerer’s Stone” (in the UK, it was “the Philosopher’s Stone”) was published in the U.S. in 1998.
While Harry Potter took the children’s and young adult book market by storm, Young Jedi Knights probably got subsumed by the unexpected fascination with young witches and wizards. Nevertheless, what originally started as a six-book series by Anderson/Moesta, extended its run to fourteen books.
“Heirs of the Force”, book one, introduces us to several new characters who would become important in later book series: Lowbacca is Chewbacca’s nephew. He is one of the few Wookies to have strong Force abilities. Tenel Ka is from Dathomir, the planet of the defeated Nightsisters, “witches” who were powerful in the Dark Side of the Force. She is the product of one of these reformed nightsisters and Prince Isolder from the Hapes Consortium. (See Dave Wolverton’s “The Courtship of Princess Leia”)
Jacen and Jaina had appeared in various stages of infancy and childhood in previous books, but Young Jedi Knights was the first real attempt to give them a series of their own. Absent from the first book (due to the fact that he was busy in his own series of children’s books, Junior Jedi Knights), Anakin Solo was the baby brother of the twins.
The plot of “Heirs of the Force” involves the twins and Lowbacca discovering wreckage of a TIE-fighter in the forest, most likely left over from the Battle of Yavin twenty years before (See “Star Wars Episode IV: A New Hope”). Jaina, who is an adept mechanic, decides to rebuild it. Unfortunately, the children also discover that the Imperial pilot, named Qorl, is also alive and has been living in the forest for the past 20 years, waiting for an Imperial rescue. He captures the children and forces them to continue to work on repairing the TIE-fighter.
The children learn a valuable lesson about when and where to utilize violence. Rather than attack Qorl (who seems slightly unhinged and unwilling to accept that his beloved Emperor is dead), the three children attempt to reason with him using compassion. It works to an extent: Qorl still escapes the planet, but he lets them live. Unbeknownst to the children, their attempt at a diplomatic and peaceful solution has planted seeds of doubt within Qorl’s mind.
“Heirs of the Force” is a quick, entertaining read. (I literally finished it during a long four-hour car ride. Don’t worry: I wasn’t driving.) It harkens back to a period in the SWEU when things weren’t as dark. It also harkens back to a pre- “new/official canon” world in which the Solos had three children instead of one, and while I think the offical canon is, for the most part, decent, I am still, at heart, partial to the old canon.
