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.

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

MC is now on the move to keep from overpowering the monsters in any one area. He finds a party member and learns that humans aren’t the only ones discriminated against. A political power with a grudge against all Keepers for abandoning the world tracks him down to try and assassinate him and his new party. He disabuses them of the notion but accidentally rips a hole in the fabric of reality letting people from an alternate timeline in and they come as conquerors. The invaders take his party and so he invades their timeline in turn. Their System is different but not in a good way. He power levels his class and makes enemies of an entire faction. He tracks down his party only to lose them again. While heading for them he faces down some leaders of the enemy faction and wins. Now not only are they enemies but the faction will be actively hunting him. Book ends.

The OP continues to be OP. The story is still fun and the pace is excellent. The world gets more fleshed out. I look forward to seeing what happens next. Please enjoy

Great series

Brooks has done it again with yet another series that is hard to put down. I can’t wait for the next book.

Adding in a mirror world

The Alternate Keeper by Jonathan Brooks.

Bax is trying to adjust to his new reality. He is the only Keeper left and forced to stay on the move. In a chance encounter, Bax meets an outcasted woman and forms a fast friendship. Until she is killed in battle. In his grief, Bax does everything he can to save her, altering reality itself in the process.

This is a great OP MC Isekai litrpg. You can just feel the guilt and loneliness coming off of Bax. He was tossed into a situation way outside of his comfort. The new character is a great addition and I’m interested to see where it goes. Miles Meili did a great job with the narration.
