I would have rated it 3 stars, but I down-rated to two for the simple reason that it's a flat, non-relatable tale. Is it magic? Hocus-pocus? Plant energy that synthesizes time? How does that work?
There's just no explanation of any sort of science. It's a rather dull MC who finds time for nothing in his life but self pity, fast and junk food and staring at TV. (Rather like millions of citizens now existing in RL).
But how did any of this happen in the first place? How did his returning to his 4th grade self affect his 40 year old self? What pulled the mysterious cord that made all of this just take place, so that the loser becomes the winner, the bankrupt becomes the millionaire, the obese slob becomes the gym bunny....nah. Not buying any of it.
If the MC had been at all likeable, it might have worked better, IMO.
I've been a practicing mental health professional for 40 years, and this is the first time I have ever heard of "Epigenetic Protein Compounds" that originate in the sultry waters and island dominions of the South Seas. It's an intriguing concept, but not likely to ever be a realization in clinical practice.
I didn't dislike the story, it was ambitiously oxymoronic; but I probably would have enjoyed it more if there's been a shred of science, at least a theory, involved. So, as a work of fiction, I would have to say it's really a stretch of imagination and therefore, has a limited market and reader attraction draw.
Now. Format. Good lord, was there a format? I noted several other reviewers remarked the same, that it might have been AI or kindle programmed, but in some sense, even the electronic world of printing fiction has to have some human input. This desperately needs an editor and a program analyst to make it less confusing. It could also benefit from a strong input by a skilled copywriter, as some of the text is just run on and stunningly stupid.
It is filled, over-burdened with grammar, tense, verb/subject issues, and I thought it would have helped if the author troubled himself to do a final review and proof, rather than trust a literacy tutorial to do the work for him. It's a lazy way to get something that just isn't readable into the mass market of e-publishing.
Sadly, the errors take a huge amount of pleasure away from the overall complexity of the text. I was kept busy correcting the grammar and syntax, rather than trying to keep a confusing and at times, senseless narrative together.
For me, that means this is merely 2 stars, and I really don't recommend it. Unless you're very bored.
