Born Without A Heart

Levy McGarden, a brilliant young agent on Fairy Tail's Intelligence and Cyber Security team, gets paired on a case investigating a new drug called Lullaby with their newest PI operative, Gajeel Redfox. Gajeel is a man with a dark past. He is used to working alone, and that's how he likes it. Between Gajeel's reckless risk taking and Levy's by-the-book work ethic, can the tension and growing desire between them cool long enough for them to solve the case?
Book 2 of the "Heart Shaped World" series.
While considered a series each book is written to be it's own stand alone story. That being said, if you enjoy this you may want to go check out Book 1, "Wicked Game".
