I couldn't remember the last time a foot of snow blanketed northern Maine as early as mid October, but here it was and here I was sitting on a stump next to a cold fire-pit at the edge of a potato field talking to myself. "You're losing it Garic, you need help, this is the twenty-first century and there are no such things as dream walkers."{i*I gave my word!{i*
"You gave your word to a red bearded elf in a dream you idiot, get real."{i* Those were no ordinary dreams and I gave my word.{i*I sighed and glanced up at the cloudless sky looking for any anomaly, but saw zip.
{i*What did he mean? I'm the one who sheds the blood and sets them free{i*"It doesn't make sense. Why me? I'm just an eighteen-year-old nobody. Why not somebody else? I know, a navy seal,they got bin Laden.

"{i*I gave my word!{i*
Not sure what those strange bracket things mean-I assume Italics

a nit pick--red-bearded? I wonder if this should be hyphenated-not sure.

anomaly-still don't like this word 'anomaly'. It leaves me wondering what is he looking for in the sky? i can't figure out if its strange clouds or something else. He is worried about something in the sky AND about giving blood. Hmmm.

"What did he mean? I'm the one who sheds the blood and sets them free" I am not sure my reaction to this....on one hand I am a bit intrigued, on the other hand this seems out of place and out of flow and takes me out of the sequence too much and also, this does not make sense.
"{i*"It doesn't make sense." IMHO, replace the word 'it' with 'none of this' or something more exacting in that vein that the eighteen-year-old character would say. I have a personal vendetta against the word 'it', unless using it is unavoidable.

""Why me? I'm just an eighteen-year-old nobody. Why not somebody else?" I know, a navy seal, *after all* they got bin Laden."

Please, do make your reader curious, care, fear or worry about your viewpoint character in your opening. Forgive me, but your opening sentence is, well, a little weird. In addition, it’s a setting, and unless your name is James Lee Burke, setting openings are risky – tough to excite the reader & tough to get past editors.

Consider an opening where Garic has a gut-twisting conversation with your red-bearded elf who forces Garic to make some kind of extraordinary promise that sounds like trouble (with a capital ‘T’). Do it in such a fashion as to make your reader emotionally involved – right from the git-go.
