On the Edge (The Edge, Book 1)

On the Edge -  Ilona Andrews I really enjoy the worldbuilding and the magic system and such, and I love the family relationship with Rose and Jack and George.

I'm not a fan of the romantic plotline, though - the problem with having a different couple in each book is that each couple falls in love and decides to get married an a fairly short time frame. It felt rushed to me. The best relationship in this book wasn't the one with Rose and Declan but seeing Declan bonding with Jack and George.
