Great characters and a good storyline.
I would have given the whole Wyrmhole War Saga a better rating if it had only gone through an editor before publishing it, or just had a beta reader go over it.
The poor sentence structure, some significant continuity issues, and other things which should have been fixed before publishing were jarring enough to 'take me out' of the story and ruin my joy in reading what would have been a 4-5 star book.
