Hi Swalker, welcome aboard!
I do have some strong opinions, but they're not worth much because the vast majority of your potential audience won't know enough about the evidence for evolution to spot any flaws in any story where it's disproven.
The only thing I could accept would be that all the evidence for evolution is correct, just not the whole story. I liked WK's idea of a coded message, so we could discover that coded messages have been placed in all genomes in all populations around the world, somewhat similar to Sagan's
Contact where a message was uncovered in pi. We're then forced to conclude that instead of evolution what we have is continuous intervention over time by some outside force or entity that tweaks genomes along what appears to be a predefined path.
I wish you all the best with your book.
