**Spoilers**
I found this story to be very bland. Like Listener said, it didn't stretch my expectations or horizons. I think the biggest problem I had was the complete lack of any strong opposition. Sure, there was some opposition, but each trial was so easily overcome that it barely felt like opposition at all: She can't get to the river near them, so she gets some forged papers (with little to no effort), she easily crosses the borders, finds a river, but it's dry, so she moves on until she reaches the ocean, and it's done. There is never any point where I felt like she might actually fail in her quest. I didn't fear for her, I didn't feel for her.
Had there been real trials for her at each junction, ie. guards who wouldn't let her pass despite her forged papers; the journey to the ocean being nigh impossible due to distance or physical impairments; threats of losing he sister's ashes, or having them taken away; in other words if I had felt like she actually had to work for her goal, and that reaching the ocean at the end was a real victory for her, I may have been more drawn into this story. But there was nothing to make me care.
The story was well written, descriptive, and solid (Not overly wordy or anything), it just held little for me. I don't regret listening, but it's not one I'm likely to recommend to others. It has been professionally published, twice now, so perhaps I'm just missing the point.
Also, I prefer my sci-fi to be a little more sci-fi. Just because a story is set in the future, doesn't mean it's science fiction.
