Being a nanny was not what she joined the Alliance for and none of the others on the mission had been given such a lowly task. It doesn’t help that his smile sends waves of lust through her every single time.

The open seas awaited him, if he could only shake his personal Alliance assigned guard, even if McKenna set his body on fire.

Finding one of few open entrances to hell will take them to the middle of the sea. But what awaits them when they find the entrance is the most dangerous thing a sailor can encounter, Sirens. McKenna and Jacob must see what passion lies between them if they are going to make it past the sea demons and rescue Kellan. And themselves.
