"As a heartless killing machine, I was a complete failure."

In a corporate-dominated spacefaring future, planetary missions must be approved and supplied by the Company. Exploratory teams are accompanied by Company-supplied security androids, for their own safety. But in a society where contracts are awarded to the lowest bidder, safety isn’t a primary concern.

On a distant planet, a team of scientists is conducting surface tests, shadowed by their Company-supplied ‘droid—a self-aware SecUnit that has hacked its own governor module, and refers to itself (though never out loud) as “Murderbot.” Scornful of humans, all it really wants is to be left alone long enough to figure out who it is. But when a neighboring mission goes dark, it's up to the scientists and their Murderbot to get to the truth.

She lives in the cloud, and travels in a phone. She’s Saga, Artificial Intelligence Detective. The exciting action of the Swiftsure Yacht race launches an adventure which ranges from the urban landscape of Vancouver to the wild islands of Alaska. Chandler Gray, a sailor and software developer, has created Saga (Say-Gah), an Artificial Intelligence app which emulates the powers of fiction’s greatest detectives.

A chance encounter with the wealthy, glamorous Gina Lee, leads to an invitation to sail on her yacht in the Swiftsure race. When Gina is kidnapped, Saga falsely claims Chan is a Private Investigator, and he takes on the rescue. Sometimes bumbling, but always determined, Chan and Saga roll through adventures in flight, at sea, and on the ground. With a band of friends providing support, and sometimes derision, Chan doggedly pursues the truth, no matter where it leads.

The quest leads to piracy in the Aleutians, a Land Rover attacked in the backwoods of Vancouver Island, and a lover’s betrayal. Saga’s remarkable abilities don't always lead in the right direction, and her sassy attitude sometimes annoys Chan, but in the end, they make an effective team.
