Shannon Thrace was happily partnered with Jamie for 14 years when he, within the span of just 18 months, decided he wanted to be a woman. Her memoir, “18 Months,” describes her confusion and heartbreak at watching the man she loved become an entirely different person — narcissistic, moody, selfish, dramatic, and very depressed. The physical changes didn’t help either. From a sexual interest in cross-dressing to Jamie deciding to fully transition, “18 Months” tells a compelling story of the destruction trans activism wreaks on people’s lives.
