Ryan Weller wants nothing more than to sail his family toward the Panama Canal and leave danger behind. But a routine dive off Grenada turns deadly when he discovers a fiber-optic tap bolted to a subsea cable and armed with an explosive charge.

 When the research vessel responsible for the device slips its moorings and vanishes, Ryan is pulled into a shadow war involving stolen technology, silenced intelligence officers, and a conspiracy intent on keeping its operation buried beneath the Caribbean.

 Caught between rising danger offshore and growing corruption in D.C., Ryan Weller becomes a loose end that a powerful network cannot allow to surface.

 Dark Signal is a razor-sharp maritime thriller perfect for fans of Clive Cussler and Tom Clancy that delivers deep-sea intrigue, covert tech, and relentless action.
