I just finished my first Sci-Fi book about the epic war between good and evil. It is a young adult story and the first two chapters can be read at: http://stores.lulu.com/store.php?fAcctID=2020066 The book is entitled Army of Heroes. It is a two part story and may be more in the future since it was a fun story to write.
If you have any comments feel free to speak your mind.
I also have the option of buying an ISBN for my book for $100, but I don't know if it is worth it yet.
