The organic computer of the Nexus has disturbed a timeless presence in Verity Space, and unleashed a force bent on the systematic removal of human influence from space-time. 

While hiding on Mars, Nomia embarks on an audacious plan to free her brothers and sisters from the Nexus, and cripple MynCorp's hold over humanity. To succeed she will need to forge an alliance with the deeply-compromised Martian independence movement. 

Mex commits to confronting Myncorp with the enormity of the alien threat. Pushed to desperation, he uncovers the sickening truth at the heart of the corporate behemoth. 

All Julienne wants is to restore her place in the order of things. She soon finds herself on the run, and operating on the very fringes of society. Her life is already inexorably entwined with Mex's. Drawn and appalled by her emotions, she must decide how far she will go to save him. 

Perfidy is the second instalment in the Verity Trilogy. Humanity's fight for survival concludes in Certitude, and mankind takes its first steps towards a post-corporate reality.
