My favourite thing about the Circle of Magic series is how, at the start, the four kids can’t stand one another.
Daja thinks of all of them as kaqs, though she respects Sandry for showing her kindness. Tris sure doesn’t trust the monstrous trader girl, or the stuck-up noble, or the thief she’s will rob her, at the very least. Briar doesn’t trust anyone, he’s just sticking around for the grub and plants, he just hopes that he’ll be able to take ‘em in a fight, even without a knife. And there’s Sandry, in the middle of it all, with a big smile, who just wants friends.
And by the end, they’re so much more than that. Sure, they might have had their ups-and-downs, but at the end of the day, they’re siblings, and they love each other, and will protect each other, no matter what.
