There were way too many characters in this book (Chediak-Higashi, Charcot Marie Tooth, Gilbert just to name a few). And they only ever showed up for less than one chapter, so it was difficult to form a connection with them. The plot was convoluted, I had to reread chapters multiple times before I finally understood them, especially the one with the brain side plot.

I did really love the main antagonist though, and she was a highlight for me. When Cancer down regulated the E-cadherins, I audibly gasped, but when she then proceeded to use MMPs to degrade the basement membrane and metastasize… One of the biggest plot twists I’ve ever read in fiction. And (spoilers!) when she was finally defeated by doxorubicin, but he succumbed to dilated cardiomyopathy in his final sacrifice, I cried.

I truly thought it was over for the characters in the micro chapter, though I do think Staph had a bit of plot armor when he developed that resistance to methicillin completely out of nowhere (yes I get they explained the altered penicillin binding protein but that wasn’t satisfying). However, it was still one of the best and most intense chapters I’ve ever read.

This is a really long book, and unfortunately you need to read others in the series (Pathoma, UWorld), to be able to understand all the references in this one. However, it did help me take step1 so that gets it 5 stars.

Some chapters were more interesting than others. I wouldn’t call it a very enjoyable read, as I had to skim some boring parts, but it was a solid book.

[Katie Boone · Rating 5 out of 5]

hope it gets picked up for a movie!!! wouldn’t recommend reading unless absolutely necessary, dragged on a bit at times and the amount of characters got to be a bit confusing at times


come back in 3 or so weeks to see if my rating changes depending on if i passed (if i didnt there will be hell to pay)

Heavy book. Not for every taste. I’m left with a bitter sweet feeling tbh. Time will tell if it was worth it.

One of the only celebrity-meeting-flexes that I have is actually Dr. Tao Le. I first met him on a Zoom call in 2021. He seemed an astute man with excellent business skills and a genuine desire to help others. It was on this Zoom call that he shared with me and my fellow members of Beta Theta Pi, Epsilon chapter (of which he was an alumnus (class of 1991)), not just advice on a successful career, but also his struggles with finding a career in medicine and the process of meeting the standards of medical boards. Having read First Aid 2025, I can also confidently say that he understands a crucial detail of the medical profession: it runs entirely on numbers.

In the fall of 2024, I began medical school. Very quickly, as many people do when entering a new profession or professional program, I started to learn the vernacular that comes with the territory. Of everything that I picked up, the concepts of high-yield and low-yield permeate my thoughts constantly. Every concept or idea in medical school that you learn has "yield." The yield of content is how frequently it shows up on a board exam, e.g., Steps 1, 2, and 3. Higher-yield topics come up more frequently, and so it is best to put more energy into learning them to maximize your chances of passing or improving your score. And I'll say it: it is concerning that a cornerstone strategy of studying in medical school is based on how content shows up on board exams, rather than, maybe, how valuable knowledge is for healing another person.

All of this culminated in what happened to me a few days ago: I took Step 1. And, really, every day I cope with the fact that to become a doctor in America is to "play the game," per se. You have to consistently prove that you are capable of thinking and performing in a way that dominant institutions designate as acceptable or useful. You have to produce certain numbers; otherwise, it's game over. The song of reducing education and intelligence to numbers is an old refrain, so I'll just leave it at that.

Soap-boxing aside, for what this book is, it is solid. Dr. Tao Le gets it. He just does. What he wanted during his time studying for boards, a Bible-esque tome brimming with only the finest and highest-yield information, is now ours. He walked so we could Step. Good luck.

most gut-wrenching book ive ever read

[Callum Robinson · Rating 4 out of 5]

I feel like I need a mneumonic for all the mneumonics

[Maira Oliva · Rating 5 out of 5]

I really liked how some characters kept reoccurring and their arc seemed the most interesting to me. The overlying theme within the book really was tied together towards the end, and when I closed the book I felt at peace that everything will be okay.

[Paige Pistotti · Rating 5 out of 5]

Enjoyable? No. Exciting? No. Too many characters? Yes. Will it make you a hypochondriac for the next 8-10 business days? Also, yes.

But it unfortunately is very helpful and the first full book I read this year. Good luck to everyone who takes it on!
