On the Edge the strong modern fantasy meets paranormal romance. The parallel worlds are fabulously created, so similar, bus also different at the same time. Little details made a really fascinating view to me, I could imagine these dimensions. I enjoyed "flashing" magic, curses, wards, the various magical changelings. The way Andrews slowly, but clearly developed a moral, that every action has a reaction and for every use of power, there is a consequence, using all the main characters. Oh, it was so just and spectacular. 
 The start was so awesome and gripping and it all went really well and so interesting. As I am spoiled by Joe Abercrombie, I was happy to get another rough-tough story bite and I did sorta got it, but with some exceptions. The main protagonist, Rose, is a real heroine: magical, kind, tough, protective to her family and even her neighbors who made her life worse. Oh, and magical children, fantastic! Both fabulous Rose's brothers are a wonderful addition with the ties between them and their relationship with Rose and Declan is touching, and adds goodness to this book. Declan is a real alpha male, who, I'm certain, made some female fans of this book sigh a lot. He's a manipulator, to get the job done, but he is just, protective and honorable. Ah, what a perfect match with a "they lived happily ever after". 
 But, as I said before, I am too spoiled by Mr. Abercrombie. The romance line in this book was too sweet and fluffy for me, that it left an overdose. To my mind it really weakened Rose as a strong and independent woman. I think I know what Andrews wanted to accomplish - she wanted a true, touching, tough story with a happy ending. Almost everything in this book seemed to unroll a little too nice and neat for me. Even the evil character, his past clearly showed that he'll turn into a bad person, so he did and for my disappointment he died in the very first book! It's just the first book, I think I needed more teasing. 
 To sum up, these weak points don't understate the story, and I enjoyed it truly. I'll read the other series of this book for sure.
