I had a hard time remembering the Edge series.. probably will reread again. Overall, the book is good. Heavy on alternate dimension's espionage, gory description on murdered subjects, very very descriptive on some imaginary monsters. But I'm happy. 
 For a romance novel, this book did fell short. But on the other hand, as an action fantasy novel, the husband-wife team score. 
 The book left me a puddle of mush and made me stay up all night reading, so, full star it is.
