As predicted, the trio are only gone for a short time, and those who love Lance, Crag and Torrent will still be able to keep track of them, even in the shadow realm. Quinn and Rollick's Norway trip may have been the tipping point in the battle against evil, for they learn how the sorcerer gains power, applies them, and Rollick also gets closer to Quinn.
Ever since the trip, I've been waiting for Quinn to get the trio's essences too. But it never happens. I think it is a good idea for Quinn would be stronger, and she would also know what the trio senses and if they are in immediate danger.
One more book, and we will be done with the series. How the team will defeat the Leviathan is still a question. It seems impossible with Quinn's condition and the evil's immense power in his belt. But, if you follow the other Shadowkind series, Sorsha, in her final state of power display, could easily burn the villain down! I hope Quinn will join forces with Sorsha!
