Here's my problem: I have three stories that follow the same theme of "Adult finds child. Adult protects child and takes child away from whoever is trying to hurt him/her." One of them is set in WWI in the Eastern front from the perspective of Vasily. The child he must protect? A German orphan who's parents had been murdered. (They had moved to Russia shortly before the outbreak of WWI.) The other two are Westerns. One is from the perspective of an outlaw named Mike Wolfletter, and another is a semi-illiterate farmer turned gunslinger. The child of the former story? A crippled Irish boy. The child of the latter story? A Native American girl who escaped the reservation. They all sound very intriguing to me, and I know they'll have to be three seperate books. I actually do want to write all three of them. My worry is that they all sound exactly the same just with a few minor details tweaked. Even if I made the protector a female, the theme's still the same. Is this a case of "pick the one you want to write the most and do it"?
