"CHAOS CLOSES IN ON THE EMPIRE OF EARTH
In an Empire of intergalactic proportions, some space piracy is only to be expected. But not on the massive scale of the operation that is now beginning to cause havoc across the whole of the known Universe. There is only one organization that could be behind such an immense threat to the supremacy of the Space Navy - the brilliantly evil conspiracy of Lady A and the mysterious C. Their plan is nothing less than the conquest of Earth and the Empire.
With top-secret information leaking to the enemy, only four people can be trusted with the dangerous assignment of stopping this terrifying revolution. They are Jules and Yvette D'Alembert and the spouses they have just married, Yvonne and Pias. But this time, even the extraordinary Family D'Alembert seem to have taken on more than they had bargained for...
Planet Of Treachery is the seventh volume in the spectacular space series featuring the amazing Family D'Alembert."
