In an uncharted island called Dijon Island, humans are classified into three races: the avaries, the mafias, and the cannibals. MAFIAS, the richest among the three races, are the notorious criminals in the island. Every malefaction they're involved in, they can easily get away without being caught. Thanks to the privilege of living beyond the Frontier Horizon. The cannibal attacks? Those are out of their worries, for their unusual blood got them covered. But all of that changed when cannibals start attacking them. Not as their preys, but as their sacrifice to a ritual. The peace is completely destroyed. Their protection is now voided and no longer useful. Their death is coming. The war has begun. - Book cover made by: @KrungRi_Gizibe

Time's running out, three more years and the case will go cold.

Until an opportunity suddenly popped out out of nowhere and made her realized something. What if she's the lacuna?
