Blood Between Us. Blood Between Us, #1

Aria Sinclair has spent years ruling her family's empire with cold precision, protecting a legacy built on blood, power, and secrets no one outside her inner circle can ever touch. Malachi Vaughn, kingpin of New Orleans, commands his world with an arrogance born of power and a hidden life he'll kill to protect. Their empires are built on blood and violence. He and Aria should have destroyed each other a long time ago.
Instead, the blood between them has been hidden behind distance, silence, a burner phone, and the son they both refuse to let the world claim. Now something bigger than their private war is moving through the city. A new enemy is carving into both empires, exposing weaknesses, testing loyalties, and forcing Aria and Malachi into an alliance neither of them trusts. Old enemies resurface. Family lines begin to crack.
And the past they buried starts pressing its way back into the light, carrying truths that could destroy everything they have built. With their son's future caught between two bloodlines, Aria and Malachi must decide whether the bond between them is their greatest weakness or the only weapon strong enough to survive what's coming.
