Some of the great ones are 'The Han Solo Trilogy' by A.C. Crispin. It delves deep into Han's backstory, his early adventures, and how he met Chewbacca. It gives a lot of insights into their relationship and how they became the iconic duo we know from the movies.
It's most likely a prequel. Since it focuses on Chewbacca, it might tell the story of his life before his adventures with Han Solo became well - known, so it would be set earlier in the Star Wars timeline.
I'd also recommend 'Scoundrels'. It has a really engaging plot that doesn't require a ton of prior knowledge of the 'Star Wars' expanded universe. The story of Han and Chewbacca in this heist is exciting and will draw you in right away.
In 'Solo: A Star Wars Story', Chewbacca is a crucial part of the adventure. He has his own unique personality. He's not just a sidekick but a character with depth. He communicates in his growls and roars, which Han Solo can understand. His relationship with Han is central to the film, and together they get into all sorts of scrapes and heroic deeds. He's also recognizable by his furry appearance and his bowcaster, which he uses effectively in combat.
The main character is Chewbacca. In the Star Wars universe, Chewbacca is a well - known Wookiee, a large and furry alien species. He is Han Solo's loyal co - pilot and friend, and this story likely focuses on his adventures, perhaps even some of the events that led to his relationship with Han Solo.
