'Fermion Quirk's twin brother Boson Quirk is dead, head down in the bog of stars and circled by his angel-birds.

'Now everybody looks sideways at Fermion, and wonders if she'll go the way of her cursed twin. Pa talks about everything but Boson, and Moo won't talk at all. Then the new voice begins rising inside Fermion, telling her she's the only one who can save her family.

'But, is it safe - is it even right - to do what the voices tell you?' (From the publisher's website.)
