Ok, when I started the tsory, I liked teh concept. But, it has become cliche and there are some inconsistencies and unanswered questions. I thought it totally unrealistic, that they both "felt" a connection and were saying 'I love You' so soon-however, if you're peddling the 'love at first sight' cliche then it can be believeable. I was also confused, was liana (you also referred to her as luciana) and her family supposed to be muggle royalty or some type of magical french royalty? She obviously knew of magic, so is she a witch? Or is she just informed of magic? If she is a witch, wouldn't it be a good idea for Harry to obtain a wand for her?
Also, after Harry has had years of training, I find it rather amazing that Liana can easily convince him to go shopping. If he knows of the dangers and he truly loves her, he shouldn't have indulged her, he should've convinced her to stay or to just take her to see her family and get more protection asap.
