The Fatal Mind is a fast-paced medical horror thriller written by N.J. Gallegos, published by Winding Road Stories. What promised to be the definitive cure for migraines will end unleashing a wave of horror when its secondary effects are discovered, starting a race against time to find a solution.

Shawn Gilbert's NBA career was cut by the headaches; after trying all the possible remedies for the migraines, he hears about miraculous chip developed by Dr Aldea Absinthe. After experiencing it by himself, he becomes his biggest advocate; however, with time, his personality starts becoming darker, and other patients develop unexpected episodes that threaten to break with Dr Absinthe's success. Either they solve it soon, or it may end with a tragedy for Gilbert and his wife, Rachel.

From the three perspectives, we become part of how their lives are running towards their ruin: in the case of Dr Absinthe, she's about to lose all his prestige and work if her chip provokes these changes; while in the case of Gilbert and Rachel, it's how Gilbert slowly becomes more violent and prone to aggression, becoming dangerous for those close to him. While Rachel and Absinthe are working on solving the problems, the perspective of losing the cure to that migraines is not an option, because of how incapacitating those headaches are.

Despite the prose can be seen as a bit dry, it is true that pairs well with the fast pacing. Gallegos puts a great care into accurately recreating how an emergency room works, and the medical details are amazingly portrayed; without losing the focus on the horror elements that, at the end, tie all together.

The Fatal Mind is a great horror novel, perfect if you are looking for something fast and that you can devour in one read; if you think about a Black Mirror episode, this novel could perfectly fit it.
