After she escapes the Twolegs who captured her, Leafstar thought her troubles were over. She, her kits, and her mate, Billystorm, are happy in SkyClan. After Harry, a kittypet, helps Leafstar escape, he asks to join the leader and her Clan, and reveals that his name is actually Sol, and Harry was just a name the Twoleg had given to him. He fits in with SkyClan and their members, but not without difficulty. Leafstar mulls over Sol, and while she's happy about his willingness to learn new things, she is more than bothered by his progress altogether, and wonders if he'll be a good fit for SkyClan.
Beyond the Code also features a look into the life of Sol, dating back to before he was a Twoleg's kittypet. This look into Sol's past features his mother, his siblings, and even the reason he wanted to become a SkyClan warrior in the first place. Fed on stories of sky warriors, Sol longs to become one of them. His mother tells Sol that they are just stories, but long after he grows up, he still believes in those stories. When Sol is finally given the chance to prove himself, he has some slip-ups. Will Sol ever be able to become the sky warrior he was told about in stories? Read on to find out!
