★★★★★ | BLACK TANK by Wade Prull
I finished Black Tank and I genuinely need a minute because WHAT did I just read?
This book was incredible.
It is the kind of psychological suspense that doesn’t need to constantly scream at you to create tension. Instead, it quietly gets under your skin and makes you increasingly uncomfortable until you realize you’ve been holding your breath for the last several chapters.
My heart was RACING while reading this. I was second-guessing everything. Analyzing every detail. Reconsidering what I thought I understood. And, perhaps most impressively, I felt like the book trusted me enough to figure things out for myself.
That trust in the reader is one of my favorite things about this book.
Black Tank follows Gary, a man who has spent four years living by procedure after the loss of his wife, Claire. He moves from campground to campground in their RV, repeating the same carefully controlled routines. Monitor. Measure. Empty the black tank. Repeat.
And that procedure becomes so much more than a literal routine.
It becomes a way of surviving.
A way of containing grief.
A way of keeping the past at a manageable distance.
And eventually, a way of avoiding what he knows.
What I found so fascinating was the way Wade Prull explores moral injury and trauma through the language of procedure. Gary has essentially categorized his own trauma into systems, measurements, rules, and routines. If everything can be controlled, perhaps nothing else has to be confronted.
But eventually, the system starts to fail.
And when it does, everything Gary has been trying to contain starts leaking through.
There was something incredibly effective about the way this book portrays grief—not as a singular event that happens and then gets “processed,” but as something that changes the way a person moves through the world. Gary isn’t simply remembering Claire. He’s carrying the consequences of what happened with him everywhere he goes.
This quote absolutely destroyed me:
“Human beings assume catastrophic events register in the ambient world. They expect that the brilliance of light changes, that ordinary objects behave differently, that the world outside the body acknowledges what has happened inside it.”
YES.
That feeling of something enormous happening inside you while the rest of the world continues completely normally is such a devastatingly accurate way of describing grief and trauma.
And then there was this:
“The reading shows a husband who is past his rated capacity and has been operating in the failure range for so long that the failure range has come to feel like operating range.”
I had to stop.
Because THAT is the book.
The idea that dysfunction can become so familiar that we stop recognizing it as dysfunction. That the state we’re barely surviving in can eventually start to feel like our baseline. That sometimes you don’t realize how far past your limits you’ve gone because you’ve been living there for so long.
And this quote might be my favorite:
“I drove through towns I have never returned to and whose names I did not log because logging them made them places I had been rather than roads I had taken. Roads I had taken were less permanent than places I had been and I needed everything to be less permanent. I needed the world to be a thing that moved past me rather than a thing I was in.”
EXCUSE ME???
That is such a beautifully painful explanation of avoidance.
Gary doesn’t want to belong anywhere. He doesn’t want to establish permanence. He wants to keep moving because movement means he doesn’t have to stop long enough to actually exist inside what happened to him.
And I think that’s what made the suspense work so well for me. I wasn’t just wondering what happened?
I was wondering:
What is Gary willing to admit happened?
What is he willing to remember?
What happens when the systems you’ve built to protect yourself become the very things keeping you trapped?
This is a book that asks some really uncomfortable questions about grief, complicity, responsibility, trauma, and the distance between knowing the truth and actually acting on it.
And I LOVED that it didn’t spoon-feed me the answers.
There were so many moments where I found myself going back through what I’d just read, questioning my own interpretation, trying to decide what was being said versus what I was supposed to infer. It made me an active participant in the story rather than someone being handed information.
That is SUCH a difficult balance to pull off in psychological suspense. Give the reader too little and the story becomes confusing. Give them too much and the tension disappears.
Black Tank found that sweet spot for me.
It is atmospheric, deeply psychological, quietly devastating, and increasingly tense in a way that had me LOCKED IN.
And honestly, I think the title itself became more meaningful the further I got into the story. The literal procedure of emptying the black tank becomes this almost perfect metaphor for what Gary is doing with his own life: repeatedly trying to dispose of something unpleasant, contained, and unspoken—without ever actually dealing with why it’s there in the first place.
There is something deeply unsettling about watching a person build an entire life around not confronting the thing that destroyed their previous one.
This book made me think.
It made me uncomfortable.
It made me question what I thought I knew.
It made me reread sentences because they felt like they had more underneath them than I caught the first time.
And most importantly, it trusted me to get there myself.
Black Tank is not just a psychological suspense novel about a man traveling around in an RV.
It’s a story about grief, moral injury, trauma, complicity, avoidance, and what happens when you can only keep running from something for so long before the road eventually runs out.
Absolutely incredible.
This is exactly the kind of psychological suspense I want more of: smart, atmospheric, unsettling, and willing to let the reader do some of the work.
Wade Prull, you have my full attention. 🖤
