I have just read this story in one sitting, and I found it to be very enjoyable.
First the suggestions: Garzulan's joining Javen was rather abrupt...though, I think you smoothed it out a bit. Also, I assume everything with Javen's dead mother and all that will be explained?
Now the praise!
I think Javen, Leah, and Garzulan have good chemistry, I loved their dialogue. Garzulan is fast becoming my favorite - his knowing yet freindly manner is very intersting and refreshing.
Javen's background has also caught my attention.
Just a question: How is Leah a captain if she is only 19?
You have a good start here and I think this story has a lot of potential. Keep up the good work - happy writing!
