While the drug treatment in this novel does not currently exist in its entirety, the altering of both the factual and emotional memories of trauma is at the forefront of emerging research and technology in memory science. Researchers have successfully altered factual memories and mitigated the emotional impact of memories with the drugs and therapies described in this book, and they continue to search for a drug to target and erase those memories completely. While the original intention of drug therapies to alter memories was to treat soldiers in the field and mitigate the onset of PTSD, its use in the civilian world has already begun—and will likely be extremely controversial.
