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.

great series

has a new twist to it mc is still op an getting stronger cant wait for the next book

OP Keeper, Nonstop Action

Walking through Derelya in this story feels like living inside a power fantasy with teeth. The stats are broken, the System pop-ups are constant, and combat hits fast and hard, but there is always a cost to unleashing that much power on a world that already fears you.
​

What really stands out is how being overpowered never makes things easy. Traveling alone, poisoning the land just by staying still too long, losing someone in a fight that should have been a victory, and then pushing past the System’s limits to fix it, all of it makes every win feel intense and dangerous instead of effortless.

An unpredictable sequel

An unpredictable sequel. I didn’t predict the direction this book took. The Retrogression System made more sense to me after this book. I enjoyed the MC’s OP nature. I’m excited to see what happens next. The narrator did a great job.

Fun read!

Basically binged book 1 and 2 back to back and now I have to wait for 3!
