Thanks to everyone who read Earthcrosser and got back to me with comments! I am pleased with your responses and very, very excited to start my third draft.
The main comment I've heard is that the setting is not consistent. Towards the end of the book, all of a sudden there are helicopters, guns, trucks, military bases, and all sorts of things that must have been hiding just over the ridge if they could descend upon us so quickly and save the day. It makes the reader wonder why the characters had so many problems due to lack of technology at the beginning of the book.
I have some good ideas for ways to fix this. Hee hee.
If any of you have other remarks, you can put them in the comments or e-mail them to me.
