Patricia Anthony’s critically acclaimed debut novel, Cold Allies was selected by Locus Magazine as the best first novel of 1993.

Cold Allies—Friend or Foe?

Into the crossfire of a great World War, into its last desperate struggles, a new, enigmatic player intervenes: A force of aliens who appear as cold blue globes of light hovering over the bloodied battlefields of a dying Earth.

Sometimes they save lives. Sometimes they kill ...

... and no one knows what they want or which side they’re on.
