I really enjoyed this book, but am giving it 4 stars because of the many inconsistencies in it. This story is exciting and original, and delves unexpectedly into the psychology behind people's actions. The author also weaves greek mythology into the story is a nice touch. Each chapter alternates between the main character, Jan in the present (who is chained in a cell, with no memory of how she got there,) and Jan a week ago in the past (who is recounting the events leading up to her present imprisonment.) We learn early on, that the past Jan lies extensively about anything and everything, but is fortunate to have 2 rich acquaintances (Simon & Melissa) who are paying for her trip to Greece to join them for a reunion party. Joining the 3 for the reunion party, are Marcus, Jan's ex-boyfriend, another couple (Brad & Kristin), and Gretchen, a woman she has never met before. The book reads quite a bit as a "whodunit", in regards to who has chained up Jan. The author masterfully writes in a suspenseful way, that it is easy to believe that any of her 6 reunion mates could be guilty, along with the possibilities that Jan is lying about the whole episode, or that an outsider unrelated to their reunion party is the culprit. Most surprising was the reason behind Jan's captivity, which in retrospect, the author had dropped several clues about. Throughout most of the book, the different characters are intriguing and believable. However, the book was also full of inconsistencies that I found greatly annoying. Most prominent as it carried through the entire book, extremely near-sighted Jan loses her glasses very early on in the book, then the rest of the book has her alternating between describing things at a distance that she could not possibly see, or has her lamenting being unable to see things that are much closer to her than some of the previous things she had described. There were many other little inconsistencies. To list some of the more prominent ones: 1) Jan while chained to the wall, lamenting that her arm stretches a millimeter short to grab a nail, when it seems obvious that she should stretch out her leg and grab it with her toes, 2) Jan being immediately affected when walking into a room full of carbon monoxide, but the carbon monoxide having no effect on another character that walks into the room, not to mention the other characters who had been exposed to the carbon monoxide for hours not already being dead 3) Jan's escape from being chained in a way that does not seem at all physically possible short of a huge adrenaline rush which she did not have, 4) Jan not having any thoughts or concerns about water, despite being chained up for hours without any water (not to mention she had no thoughts of any other human concerns, such as food, going to the bathroom, or being cold.) 5) the trial scene where the guilty party inexplicably takes the stand, even though Greece does protect against self-incrimination, 6) admittedly I don't know Greek law, but it seems unlikely that "multiple life sentences" would be given to someone for manslaughter and attempted murder 7) and admittedly this is a minor part, but when Jan mentions that her bra is "soft and comfortable"...um just no, bras are never soft or comfortable for the woman wearing them. Overall, this is a book that is worth reading and thinking about, but it is unfortunate that there are so many inconsistencies distracting from the story.
