Oh I'm so torn! I love Morningstar Mondays and there are tangents of the story yet to be told (about Kellar's father and pack for example, or his uncles. Are we positive they're dead?). On the other hand there is something to be said about "leave them wanting more," and you've done that in spades. Bottom line: I'd be thrilled if you continue to book 2, but am satisfied with the journey you've taken us on in this world.
Btw: I loved that Fendral played such an important part in the hunter storyline. Without him thing could have ended a lot differently. I also loved how he was instrumental in Keller and Tobyn meeting. But for the old grey wolf, Tobyn would have kept on driving.
You should be proud of this story, Gary. You entered the Shifter-verse and took us on a journey that was unique and exciting: a feat hard to accomplish in this genre.
