Fair Exchange - Amsterdam Institute, #3

Over a century after the events of Dirty Burnout led to the founding of the Amsterdam Institute to help those struggling with the spread of internal-technology, a new adventure begins. After a year as a civilian mistakenly held by the LSF planetary alliance in a POW camp, Sienna has been offered a chance at freedom, but one that comes at a staggering price. LSF shoved a dead Pax Romana spy's implant into her head and sent her in place of that spy in a prisoner exchange.
Now, not only does the Pax Romana empire blame Sienna for the deception, but the implant is leaking, eroding her sanity with scraps of personality and memories of torture. Worse, she must have been expected to die of the procedure once the exchange was complete, because now someone's trying to finish the job. Trapped at a Pax Romana facility with no one she can trust except perhaps the building's Near-AI, Sienna must find a way home without losing her life or her self.
