|Please say there's more to this story. Being a fan of the legend of Atlantis, the title caught my attention. So, naturally I dove in.
You left me wondering if the drug will kill Marcus or simply knock him out for a time, long enough, for Marcus to miss the event.
I have to say up front, I'm not fond of killing characters in the first few pages. So, I'm hoping he's simply drugged out.
That said, there's a story here. What few words you have inspired a full scenario in my mind. This is not easy to do. Keep writing and please keep me posted on your progress. I want to know more.
On to the technical issues. I see the same problem that I had with tenses. I can't count how many teachers, mentors, and fellow writers have proverbially smacked my hands for over using gerunds ( words ending in ING and LY). There's no hard rule that says never use them. Still, it's advised to use them as little as possible.
About this being a prologue- why not take it all out and make it a full chapter? Flesh it out and use it as chapter one to set the story.
In closing, I would like to recommend a book. I share this only with fellow writers who's script has caught my imagination. Self-Editing for Fiction Writers, 2nd Edition: How to Edit Yourself Into Print Amazon link: https://tinyurl.com/y9jqr7er
This book has helped me in more ways than I could have imagined. I hope you get as much out of it, if not more.
Best of luck with this. I look forward to reading more and seeing how this story unfolds.
