Boston private investigators Patrick Kenzie and Angela Gennaro's relationship has hit the skids — their longstanding professional commitment and growing romance have disintegrated because of seemingly irreparable personal differences. Despite these problems, Prayers for Rain brings them together again to hunt down a predator whose modus operandi seems to put him beyond the law.
This killer's insidious weapon leaves no smoking gun and no bloody knife — just merciless manipulation that drives his victims to despair and ultimately to take their own lives. As Patrick and Angela attempt to identify and save his next target, the killer turns his attention on them, beginning a dangerous, tormenting game of psychological warfare in which mere survival is a mixed blessing — even the winner will not emerge unscathed.
