Kate McCann's book is, as you might expect, very emotional and puts across Madeline's parents views on her disappearance and the subsequent police investigation. Of course this means that the abduction theory is the only one presented in the book. At times, particularly when discussing why she left her children alone in the apartment, it comes across as over-justifying her and her husband's actions but essentially seems like an honest and not over-exaggerated account. There is a particular focus by McCann on her family's treatment at the hands of the police when they were declared suspects in the disappearance, and at times it is easy to see how horrific it must be to be publicly accused of such a crime, and feel that the real abductor was getting away. The despair is palatable.
However, the book does not answer many key questions surrounding the case and, as expected, is very one sided. There is also a lot of criticism directed at others involved in the case, such as the hotel staff, police and other residents, some of this unjustified and which comes across as a ploy to increase the reader's sympathy for the McCanns.
Overall the book is vivid and detailed, although some of the recollections are dubious because of their detail, and although it presents a one-sided view of events, it is very readable. The purpose of the book is dubious, the official line is that it will raise awareness and the profits will go to the fund to help find Madeleine, however, from some of the content, it seems more like retaliation for all the police leaks about the investigation, at a time when the McCanns, by Portuguese law, could not speak out.
I wouldn't recommend this if you want a broad, unbiased overview of the case, but it does provide a good insight into her parents' feelings and actions.
