Similar set up to the other prequels.
This one follows Briar and focuses a lot on her relationship to her brothers.
I love the puns and word play in this series: hexcitment, MirrorChat, spellbinding. Even if the slang terms don't always make sense (why is "hex" used as a positive word?), it is still fun and adds an interesting element to the text.
As with the other prequels, Briar appears less shallow than in the show, which creates an interesting story and a likeable character.
