Some may find it unbelievable that a 20-year-old Oregon woman could be enslaved by a sexual sadist for seven years--that even after being able to move freely during the day, she would allow him to lock her into a wooden box every night. Perhaps it's a minor failing of this book that the authors do not elaborate on the psychology that made her such a "perfect victim." In other respects, though, the story is well told, with an impressive accumulation of details: the woman's capture, the tortures she endured, the brainwashing techniques, the fiendish contraptions her captor constructed, the slave contract he made her sign, and the increasingly strained relations within the peculiar family that included master, slave, wife, and child, all inside a single-wide trailer. As well-known attorney and author Vincent Bugliosi writes, "A gripping and disturbing story of the secret life of apparently normal people. At once, horrific and engrossing."
