***Book Description***
 
After almost seven years trapped inside his twin brother, Xavier's soul is finally stitched to his own body again, although he is physically weak from the long years in a coma. Death Princess Willow is thrilled to have her fiancé back, but her duties as Grim's emissary takes precedence when the Reapers' war with Everland intensifies. And now tension between the Ocean and Sky realms threatens the fragile balance of their world. Even the Demon kingdoms are fighting among themselves.

Tasked with a crucial diplomatic mission, Willow sets sail with the twins and their loyal companions, including several royal Relicblood heirs from all five realms. Their dangerous journey will take them to the icy glaciers of the Ocean realm, then on to the lush forests of the Neverland continent.

But the ruthless new queen has laid an ominous trap for the legendary Shadowblood twins... and the reapers are sailing right into it.
