|La maga de riñones, by Marisol Robles|
You can follow Marisol Robles on her blog Diario de la sed (Diary of thirst), which recounts her progress. (Google translate does a pretty good job on most of her posts...Kidney patients on dialysis are thirsty, since they have to time their drinking to their dialysis sessions...)
P.S. Susan Rees, the nurse transplant coordinator celebrated in the poem, is also the wife of Mike Rees, the founder of the APD, who organized the very first non-simultaneous kidney exchange chain.
