There is tension at the university. The campus police are pressing for greater fire-power. The controversial new university president, a retired military intelligence officer who saw action in Iraq, needs to make a far-reaching decision. Faculty concerns about guns on campus must be weighed against student safety. The intern psychologist at the student health center has a new and potentially violent client she worries might be stalking her. Is he a threat? Could he be the next campus shooter? Lying darkly under the elegant landscaping of the university is an elaborate network of floodwater tunnels and drains. Designed to prevent risks, do they now represent danger? Like the tunnels, the questions in this thriller keep twisting and turning.
