COVEN OF ANDROMEDA

Coven of Andromeda centers on a group of young witches bound together as a coven, and the story kicks into gear when ancient powers wake up and put that coven in danger, forcing its members to get a real handle on their individual abilities fast. At 1,034 pages, this is a genuinely long book, catalogued for ages 12 to 18, so it's aimed squarely at teens rather than a middle-grade crossover, and it's a serious page-count commitment even for a dedicated fantasy reader in that range.

The story leans on the relationships between the witches as much as the magic itself, with loyalty and trust between coven members tested alongside the external threat from the awakened powers. That combination, a magic system with real stakes plus a tight ensemble cast working through their own friction, is what the book is built around rather than a single hero's arc. Given the length, this suits a teen reader who wants to settle into one long fantasy world for a while rather than someone looking for a quick read between other books.
