Distorted Perception by Trish Arrowsmith is the type of book that even though you like the book you know you probably won't be able to read it again (for those of us who regularly rereads some books).
My statement above is not a criticism, it is a compliment. When an author makes the interactions between the characters realistic yet disturbing, it makes for a great read. But because it stirs strong emotions in the reader (for me, mostly anger, compassion, and frustration) it might not lend itself to a second reading. An example from a completely different medium is the film Schindler's List. Powerful movie, glad I saw it, don't think I can sit through that rollercoaster again.
I think (hope) this novel is also a bit eye-opening for people. While most people won't experience anyone quite as extreme as Maxwell, we do regularly meet and get to know people who manipulate others for their own ends and/or enjoyment. Maxwell used many of the techniques these people use, and Arrowsmith gives us a glimpse into how Kathleen did, and by extension the reader can, misread what is happening until it is too late. One doesn't have to run and hide from interpersonal contact, just pay close attention to anything that might be unusual ("too good to be true," making big decisions too quickly, etc).
While I would recommend this book to anyone who enjoys dark suspense or life stories, I would perhaps warn them about the extent of the manipulation and violence (physical, mental, emotional) so they can decide whether a dark but realistic book is what they want.
