In this attack her father tells her to get behind him and grabbing the axe, he goes off to get the Wood Monster. When the Wood Monster comes, Donna's father tries to hold it off, but fails. In the fey attack she almost lost both her arms, after they got bitten by the Wood Monster. Maker saved them by binding her lower arms and skeleton in pure star iron and silver and marking her with magic. Donna is not sure whether it's because of her father's death or the fey attack, but her mother has gone mad and only very rarely remembers who anyone is.
Ever since then she has been involved with the hidden world of magic, as her parents both belonged to the Order of the Dragon, an ancient alchemist society. Only when Donna's best friend Navin Sharma is take by wood elves, the worst kind of fey there is, does Donna accept who she really is. With the help of her new-found friend, Alexander Grayson (Xan), she rushes head-long into the deepest and darkest place there is.
Karen Mahoney has captured the prefect teenage novel, action, drama and romance, in The Iron Witch. Being the first in a series it will make for a wonderful read. I highly recommend it to all teen readers. You will enjoy!
