The book Boundary Crossed was written by Melissa F. Olson. It’s a story about a boundary witch and her niece, which happens to be a null. There are also vampires and werewolves involved in the story. It defiantly fits in the supernatural genre.
I loved this book. The characters were compelling and the storyline kept me guessing until the end. The book was well written and very original.
I give it an A+
