Publisher:Quartet Books

Part of the Namara Group, along with sister publisher The Women's Press. Shares same ISBN prefix 07043.

Confusingly, several Quartet Books (like this) clearly have the Orbit Logo on spine and cover, though the Quantum logo (a big "Q") usually appears on the reverse or internally. Going by the 07043 ISBN prefix usually clears these up, although it would be interesting to know why this mix-up occurs.
