There is SO MUCH going on here. Too much, I'm afraid. While the pace helped keep the narration clear of the very much dreaded "traveling time", the complexity of the world created politically, geographically, and othersidelly(?!), would have benefited from a few more detail in the narrative. 
 The characters are likeable and very competent, a novelty that I appreciated, and I guess it didn't really bother me until the Vermillion plot develops. Everything happened so fast that it was confusing. (view spoiler)[ Nynnia is a being from the Otherside now she is going to protect its foci now she loses her immortallity. Total space of writting: a page and a half. (hide spoiler)]It was way too hectic and it looked messy, so much that it took a star off the rating. It bothers me too that we are left wondering who she is, and I feel that with such speedy development she will be forgotten on the following books. 
 For now I'm going to leave the series in a "pick this up again if you ever own an e-reader" shelf. But it struck me as a lovely summer read, very enjoyable overall.
