The Fault Tree: A Thriller set in India — Mickey Friedman

Ten years ago, Marina Robinson followed her younger sister Catherine to an ashram in India to save her from her blind devotion to Nagarajan, a mystical guru. But Catherine was killed in a tragic fire and Marina returned home alone. Now Marina is an engineer for Breakdown, Inc., a San Francisco firm that fixes blame -- for a fee -- when something goes wrong. Something like the fatal collapse of the Loopy Doop ride at Fun World Amusement Park. To begin work on this, her most important case, Marina must construct a fault tree -- a diagram for determining cause and effect. Then, just as she's nearing a solution, Marina's life -- which she's carefully constructed to block out the past -- is disrupted by a mysterious series of messages. From India. From someone who knows things about her that only Catherine knew. Or knows. Could Catherine still be alive? Abandoning the Loopy Doop project and rushing to India, Marina is drawn into a perilous and macabre chase that forces her to confront long-buried questions about Catherine, the guru, the ashram, the fire -- and the fault tree of her own life.
