Cross Your Heart // Regulus Black

The Sacred 28 families are some of the most powerful wizarding lines in the world, and their purity is guarded carefully. Many a pureblood has been forced to marry for blood rather than for love, but no one takes it quite as seriously as the last of the original sacred families. They marry for status, not for love. Never for love.

With the families dying out and the old traditions fading into distant memory, it's never been more paramount for the Sacred families to make powerful matches for their children. Preserving the pureblood lines and the magic that runs through them is of the utmost importance. The Black Family Dynasty is more than familiar with the traditional customs, and no one has arranged a more powerful match than Walburga and Orion Black.

A Gaunt and a Black. An inconceivably powerful alliance, two of the most prominent family lines in wizarding history, finally connected. Their son, their heir, matched with a Gaunt? They couldn't be happier.

Magdelyna Merope Gaunt, the daughter of Morfin Gaunt and the cousin of Tom Marvolo Riddle himself. She could never refuse such a match- no good pureblooded girl would ever dare to turn away a member of the House of Black. And with her family nearly eradicated, she has no choice but to marry. Who better than Regulus Black?

The only complication? The wizarding world is teetering on the edge of a war, and Regulus is right in the middle of it. When a prophecy complicates matters, Regulus and Magdelyna have to work together to stay alive, caught up in a game that neither fully understands: a game that stretches through time, that defies the laws of life and death. When the side of good isn't completely good and the side of evil isn't completely evil, they have to find a middle ground.
