Exile of the Mind: Ghosts of Triton 1. Exile of the Mind, #5

Darren Vaughn has suffered a humiliating betrayal by Henry Withers, the spy who'd swapped bodies with Vaughn's lover to infiltrate the rebel colony. Now Vaughn takes his revenge by sending his forces to strike at the heart of the UN's flagship high above the planet. In a desperate attempt to save the leaders, a young male nurse named Jack Thomson is forced to swap bodies with UN General Carver, only to watch her escape pod crash somewhere on Triton.
Now in the General's sensual older body, Jack has to find her before the rebels do and put an end to mind isolation technology once and for all. Jack is curious about his new form, and the remnants of General Carver's mind are making him ache for his new bodyguard and fellow solider, Henry Withers. But the price of ending mind isolation for good may be more than Jack is willing to pay. The penultimate book in the erotic sci-fi thriller series Exile of the Mind!
