The Alternate Keeper

An OP MC Fantasy Isekai Adventure (Retrogression Keeper, Book 2)

By: Jonathan Brooks

Narrated by: Miles Meili

The Lone Keeper has an entire world to protect, but that world is about to get a whole lot bigger…

After discovering that his presence in Derelya has a detrimental effect on the ambient energy if he stays in one place for too long, Bax is determined to keep on the move. Forced to go solo after his Party abandoned him, his entire goal is to learn more about the world he is duty-bound to protect, while also attempting to gain the support of the population–all despite being one of the despised Keepers.

On his travels, he stumbles across an individual who is just as much of an outcast as himself. Teaming up, Bax hopes to one day help the new addition to his Party get stronger and potentially even become another Keeper to join him in his efforts to save Derelya from the monsters that threaten it…

…until a Task to defeat a Remnant goes sideways. Despite eliminating the powerful monster, his new Party member is unfortunately killed soon after; in an effort to get her back, Bax accidentally does something that will change the world–and the entire Retrogression System–forever.

This story contains an overpowered main character, LitRPG progression mechanics and stats, and isekai/portal fantasy elements. Contains no sexual content or harems.

Alternate timelines + dungeon grind = numbers go ⬆

Jonathan Brooks cranks the dial to epic in The Alternate Keeper, where Bax’s journey explodes into alternate timelines and a training dungeon that’s basically a paradise for stat junkies.

This sequel doesn’t just expand the world—it multiplies the opportunities. Alternate realities mean new powers, new quests, and wild chances to rewrite destiny. And the dungeon? It’s the ultimate grind spot, where every battle, every challenge, every clever move makes those glorious numbers go up.

With Miles Meili’s narration bringing the chaos to life, this is pure LitRPG dopamine: overpowered MC antics, universe-sized stakes, and progression that feels like rocket fuel.

If you loved The Lone Keeper, Book 2 is where the game truly levels up.

Too much power man

Having had the fate of the world(s) thrust on him in the last book, the MC has the unenviable dilemma of where to start. He's missing an instruction manual. I enjoyed the story. I do end up a bit with stat fatigue; fortunately, it only shows up occasionally. I've enjoyed most of Jonathan Brooks' stories, and this one did well holding my interest.

Hard Fall Off

Unfortunately this book falls off hard compared to the first one. I disliked how convenient some things in the first book were but it evened out after bax finally entered the world. It is honestly insane how much of this books plot is nonsensical, and very convenient for the author. A good chunk of this book is stuff simply happening to the MC and the MC having no agency, except to react. So many situations are overplayed and dragged out through padded dialog and inner thoughts. I am dropping this book with only 2 hours left to finish but now the person he needs to save magically got warped away for whatever damn reason. So now the author can artificially extend the story even further. I would also add that every time the MC gets ambushed, it makes absolutely no sense that he has to kick his stats into gear like an old gas lawn mower. Stats are not something you can just choose to apply whenever you feel like it. Bax either has the Stats or not. You can't just choose that being surprised somehow makes him freeze for several seconds when he can kill dozens of people in the same time. I was floored every time I heard "bax was shocked and couldn't react" bax's mind would calculate and react so many times faster than a normal person that I can't even imagine it. How am I supposed to believe that he was surprised by lvl 50 people. Bax could have killed all of them within a few heart beats, if the author didn't just make stuff up about how he has to kick his reaction speed into full gear in an attempt to make bax weaker. P.S the unity paralyze ability was stupid in book 1 and it's stupid in book 2. It is a week plot device to artificially cripple bax when it's convenient for the author to do so.
