Thirteen extraordinary children with mysterious powers.

Their loving and protective father.

And a sociopathic neighbor who knows them better than they know themselves.

When Capricorn Munch and her twelve siblings appear outside a children's home, no one, including themselves, knows who they are or where they came from. At ten years old they stop aging, as she and her siblings develop powers that gift them with incredible abilities, like healing wounds and manifesting objects. They keep these powers secret and their adoptive father restricts their use. Capricorn strives to live a normal life, blissfully playing with her favorite sisters, witty and bold Allie, empathic and wise Breezy, and giddy and sweet Hazy.

But now a sudden threat has intruded on their carefree lives: Their next-door neighbor, a man who calls himself Big Boss. Capricorn watches fretfully as Big Boss encroaches on her family like a malevolent force, feeding hostility between her siblings and causing them to be reckless with their powers. Capricorn knows Big Boss is plotting something sinister and can only pray it doesn't end in ultimate doom for her and her family.
