Bound by an unbreakable curse, Prince Khufu and his beloved Chay-Ara are continuously reborn. The two fall in love in every new life, but are destined to be separated by death, one always out-living the other, their souls lingering until both can be reborn again. Over and over the two fall in love. Over and over one must watch the other die. Over and over cycle continues. Now, in the present day city of Magnolia, Khufu has been reborn as Gajeel Redfox, an archaeologist-turned-hero who goes by the alias of Hawkman when fighting alongside his fellow comrades. Once more his soul yearns for its other half, the half that now resides in Levy McGarden. When the two finally meet, as they are destined to do, the game of life and death begins again. A game that the two are determined to win this time. (Rated M because Gajeel has a foul mouth.)

An Angel and a demon. The two couldn't be more opposites. Yet, they seem drawn to one another, unable to stay away. When the angel Gajeel and the demon Levy meet, they are determined to stay enemies. As is the nature of demons and angels. But, something keeps luring them back to each other, and neither one is able to stop it. Eventually, the two break the ultimate rule of both of their worlds: do not fall in love. Unable to stay away from each other, the two fall into a doomed romance. One which is more passionate than either of them ever intended--or that they care to control. When their secret gets out, along with an ancient evil that they can't face alone, will the two be able to stay together? Or will fate tear them apart?

Twenty years have passed since Lucifer had been sealed away, and Levy and Gajeel can finally begin their life. However, a shadow on the horizon threatens their growing family. Will they be able to overcome the darkness from below?

Told from the perspectives of Gajeel and Levy, Lucy writes this: her greatest novel. In celebration of her dearest friend, she details the life of Levy McGarden, leading up to that fateful day. Levy McGarden, a brilliant bookworm and a talented solid script wizard, discovers a dark secret one day on a job. Throughout her investigations into the truth behind this secret, she grows close to her fellow guild mate, Gajeel Redfox. Introduced to the guild as a hardhearted Iron Dragon Slayer, Gajeel is slowly transformed into a caring man—one who would do anything for the small solid script wizard he had become so fond of. As the two grow closer, they begin to realize that they mean more to each other than that of a normal friend or teammate. They maybe even love each other. However, fate has a funny way of intervening at the worst of times.
