Shame Book

Not sure how far I'll get with this before leaving on holiday - should have opted for an anthology, no doubt.
Some of Da Costa's books are great, with real characters, real plots, good stories and descriptions. Some are not. Perhaps the title is operative term here - these characters are shadowy indeed. Sometimes black lace novels give me the impression that the author had a series of points to include - M-F, S-D, F-F, M-M... etc and the text is just filler from scene to scene. This one starts out with some promise - and then the whole mystery of Daniel's issues crumbles. At the end of the day is a mentally ill character sexy? but is he mentally ill? There was a hint there might be something supernatural, but that too faded away. So on the whole quite the disappointment for a DaCosta...
