Frost is the second book in the Stork trilogy. In this book Katla Leblanc is still coming into her powers as a Stork, which is a person who delivers souls to expecting mothers. Kat and her boyfriend Jack were just trying to enjoy her first Christmas in Minnesota when things got way out of control. Instead of fully working through their problems, Jack is distracted by the beautiful newcomer, Brigid Fonnkona, an environmental scientist. Kat doesn't trust Brigid at all, but she seems to be the only one. More problems between Kat and Jack continue, but they still go unsolved because Brigid and her team take Jack on their trip to Greenland. Kat stays in Minnesota confused and hurt, but when Jack goes missing in Greenland, Katla knows she has to find him. this book was really interesting. I dint usually see a lot of books that have Norse mythology in it. this novel contained many legends form Iceland that turned into reality. I would recommend this book to anyone who wants to read a fantasy teen romance that's out of the ordinary.
