I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
I do like the Soulfire story - part of Eternal Soulfire - and I especially like the new character they introduce, a magic user who is in danger just because of that fact. I do not care much for Miya, the old character who is apparently going to be in charge of guiding the newbie, so while I enjoyed the story in general, it wasn't great for me.
Fathom Blue also uses new characters, and while Maylander is a huge part of getting this team together, he has very little page time. I didn't like any of the new Blue characters here, so I'm going to give Fathom Blue a pass.
I'll end up doing other Soulfire series first, and look into Eternal Soulfire more before making my decision on that story.
