@packetcharmer @cute_weeds @maritroniuity OK, I finally found the book again: it's "Principles of Transgender Medicine and Surgery":
https://www.amazon.com/Principles-Transgender-Medicine-Sexuality-Hardcover/dp/0789032686
One thing to note is it's 11 years old; IDK if there have been any newer publications that address trans medical care. But, at least it's a start!
