Here’s what I had to say on Goodreads:
More Twisted Than The London River It Takes Place On. This is one of those hyper-twisted books where for much of the tale, you think you’re getting one thing… only for it to flip, then flip again, then again and again and again. Told mostly in two eras, the days immediately after a particular person goes missing and the year prior to that event, this is a tale of intrigue and, let’s be quite honest, quite deplorable characters. Seriously, if you are the type that has to “like” the characters or at least one of them… well, there really isn’t much of that to go around here. These characters are all horrible in some way or another, though hey, perhaps that is life. Overall a compelling story with an ending you won’t believe. Very much recommended.
