Will this growly protector break her book-loving heart...or become her second chance at love? Savanna Vasquez lost her Navy SEAL husband years ago to terrorists, and she doesn’t think she’s capable of falling in love again. Then came Griffin. The inexplicable connection between them has them both wondering if maybe they were brought together for another reason. And as Griffin does everything in his power to save Savanna, he discovers there’s a chance she just might save him, too.

This three-book bundle is a spinoff from the uber-popular K19 Security Solutions Teams One and Two series and takes listeners into the darker depths of security and espionage.

When innocent lives are threatened, this team has the strength and intelligence to save them. As the K19 Allied Intelligence Team One agents gear up for counterattacks, the war on trafficking ignites. Come hell or high water, these agents will take down the enemy one by one.
