'tsokay. Same flaws as the first two (utter Mary Sue-ism, abuse of the word "giggle", which occurs about every 8-10 pages, along with other writing tics), leavened by good world building and decent tension and adventure. Ain't literature but was a quick read. 
 For anyone expecting this to be a trilogy that wraps up, don't get your hopes us. Book ends on a kind of narrative cliffhanger and clearly there's a Book 4 somewhere in the wings. 
 As with Cheeze Fluffle, your mileage will vary.
