Invisible Things is one of those novels that you want to love. I mean REALLY love, but somewhere along the way from the beginning to the ending... you find that something is just missing. And this leaves you not too sure exactly what you feel about the novel as a whole.The plot starts off promising enough. Sophie's parents die when she is quite young. Under circumstances that just do not seem right in her mind. In order to come to terms with her past, Sophie embarks on an adventure that will lead her down a path that is as remarkable as it is, at times, painful.The mystery aspect of the novel quite compelling. It is a full-bodied mystery that kept me on the edge of my seat trying to stay one step ahead of Sophie and her thinking. Now while I did enjoy this aspect of the novel, I must admit that it took over a vast majority of the focus of the novel. It seemed like every time I thought Davidson was going to focus on some other element, here came the mystery again. It seemed like if Sophie was not thinking about how to solve the mystery then she was collecting evidence... and more evidence.As a whole, Invisible Things was not exactly what I was expecting. But it had plenty of redeeming qualities. A fascinating lead female who will stop at nothing in her hunt for the truth. A setting that I would love to lose myself in. And a mystery that is too far fetched to be true, but you love it anyways.
