Right before my brain surgery, my husband confessed, “I’ve had a daughter with your friend for nine years.” He believed the operation might damage my memory and make me forget everything he had done. I didn’t scream or confront him. Instead, I quietly canceled his cards and gave our financial records to a lawyer. The following day, he discovered that my memory wasn’t the only thing he should have feared.

The sterile scent of iodine and bleached cotton hung heavy in the air of my private suite at Chicago General Hospital. The rhythmic, synthetic beep-beep-beep of the heart monitor was the only sound tethering me to reality. In exactly two hours, a team of neurosurgeons was scheduled to shave a portion of my head, cut through my skull, and attempt to resect a tumor the size of a golf ball from my frontal lobe.
