Here's my dilemma...

My main character, Ethan, wakes up to find himself in a primieval world, with no knowledge of how he got here. In fact, he doesn't remember anything of the entire day before the event.

I had different theories as to what had happened to him , but looking back, they seemed hackneyed at best. Cheesy, and ill-concieved.

My question to you is, why have the loss of memory thread if you don't develop it? I would suggest to either get rid of that thread, or develop it.

I'm still trying to decide whether he figures out what happens, or if that part of his life will forever be an infuriating question mark.

I think if you have Ethan an amnesiac, you're promising to tell us why -- at least, I'd want to know. If you didn't want to tell us, you could let him remember. If he can't get back to our world, how would it harm the story for him to remember? Also, even amnesiacs know how to, say, dial a telephone, or might say, "Do you have an Internet connection?" -- which gives major clues as to his previous life in our world. Flesh out your world, and your character! I hope you won't snip off interesting inquiries like that, but bring them in, and enrich your world.

But as to how he got there . . . he may have absolutely no way of knowing, ever. If he gets an explanation, it will probably be purpose not mechanics (as in, God wanted me to learn something). I think that's ok (although exploring mechanics might also be interesting).

I also think your motivation is kind of lazy - no offense. I know that every reason you've come up with so far is not what you want but giving up is not necessarily the best choice. I would keep trying. Believe me, I know how this feels. I haven't done any books on memory loss but I did write myself into a corner in my novel where I could not figure out WHY my Lead was doing what he was doing. It came time to explain it and everything I came up with was so lame. But I felt it needed an explanation.

My solution...I changed the story. He didn't do half the stuff because there really was no good reason for it. That may not be an option for you. If it isn't, keep looking for an explanation.

You have to try and turn off that uber critical part of yourself though. If you think about it, some of the best stories of all times have the lamest plotlines if you try and explain them in simple terms.

"This little two-foot guy has to take this ring that some long dead sorcerer put all his power into, and throw it into the lake of fire. Along the way he will have to battle wizards, trolls, orcs, and this creepy, slimy guy that keeps following him around. Oh, and a gigantic spider. But he gets through it all with the help of his friends and throws the ring in the fire and saves the world."

If you have Ethan wake up with memory loss, then you're promising that eventually he'll recover his memories somehow and those memories will explain how he got sent to the primeval world. On the other hand, if he remembers everything that happened, but there is nothing in there to explain how he got where he is, then you're promising nothing.

More people will keep reading longer if you make the promise. But in the end they will be furious if you don't deliver. Fewer people will read if you're up front about never explaining that event at all, and some of them will regard it as an implicit promise that you will eventually reveal what happened, but by and large you won't arouse as much fury when you never reveal what happened.

Also, I think I spoke too soon when I mentioned amnesia. It was a split-second decision I made as I wrote the message. I do that too often, I think.

In any case, the plan all along was to have him wonder how he got there, then resolve to find a way home without really knowing what happened. His adventures throughout this world are all a result of his intense desire to go home, and to see his family again, to get back to the life he once knew. The how was never as important as the why, or the why me?.

Besides, if he (or I) never figures it out, he/I could always blame God.

Regardless, if he does end up with amnesia, I promise you, the reveal, the shocking moment when it all becomes so clear will be there, and it’ll be satisfying.

And I suppose was trying to save myself work, but not because of laziness. I’m at a stage where I can’t move on to the next scene, the next chapter, without having this scene down pat. I’ve been working on two chapters for three weeks. This phase might not last (I’m still struggling to find my writing style and habits, I suppose), but right now, it’s what works. If I skipped the explanation, I could move on.
