In Poison Pill by Anthony Lee, Dr. Mark Lin, a hospitalist at Ivory Memorial Hospital, uncovers a lethal conspiracy linking two seemingly unrelated weight-loss treatments: the herbal supplement Motileaf and the pharmaceutical drug Naxipil. When patients, including a young man with bilateral kidney failure and a morbidly obese patient with sudden pulmonary hypertension, experience bizarre, organ damage, Lin traces the source to a sophisticated counterfeit drug operation. He discovers that identical triplets Stuart, Garrett, and Rupert Wang, leaders of the Red Snakes triad, have infiltrated both a legitimate herbaceutical company (Brighter Sun Herbals) and a major pharmaceutical firm (Tixerix) to distribute contaminated products. What follows is a struggle to survive as the conflict grows quickly, including a kidnapping.

Anthony Lee crafts a diverse cast that elevates the medical thriller genre. Dr. Lin is a compelling, morally driven hero whose professional obsession becomes deeply personal when his own father suffers a devastating stroke linked to Motileaf. The antagonists, the Wang triplets, are portrayed with surprising sophistication as survivors of childhood trauma who have weaponized their medical expertise for criminal enterprise. The novel effectively explores themes of healthcare corruption, the dangerous ambiguity between unregulated “natural” supplements and Big Pharma greed, and the struggles of immigrant families. Lee’s authentic clinical details, from hemodialysis procedures to cardiac catheterizations, ground the suspense before accelerating into action. The Southern California setting, spanning the sterile corridors of Ivory Memorial, the bustling Little Saigon in Asian Garden Mall in Westminster, and the corporate offices of San Diego’s pharmaceutical industry, creates a vivid backdrop for this tale of criminal machinery. Poison Pill is delivered in an intimate, irresistible, first-person narrative voice that left me feeling as though the action took place right before my eyes, transforming the story into a page-turner.

How to Plan a Memoir That Readers Cannot Put Down

By Romuald Dzemo  · 

Many first-time memoirists believe that because the events are true, the structure will take care of itself. This is a fatal error. Life is chaotic; narrative is order.
