Loving Amari by Tessa Stone

She’s ascending to goddess. He’s breaking without her. And an ancient enemy is coming for everything they love.

Carla Blackwood is Queen of Limbo, but ruling the realm of lost souls isn’t enough to stop what’s coming. Nathaniel, a vengeful spirit with stolen Blackwood magic, is building an army to destroy Wintermoon. His target? Baby Solomon. His weapon? Possessed shifter children. His ally? Henry, the man who’s been hiding in the shadows of Brookstone and Blackburn.
Mother Fate offers Carla a terrible bargain: ascend to Guardian of Realms and gain the power to stop Nathaniel, or watch her family burn. The catch? Ascending means leaving the living world behind, bound to limbo. It means endless separation from Amari, the vampire mate whose love has become her anchor.

Three days apart nearly destroyed them both. How will they survive eternity?
Amari is a man on the edge. Centuries old, and he’s never felt this helpless. He can break any code, hack any system, but he can’t protect Carla from her destiny. As she grows more powerful, more ethereal, more distant, he’s forced to watch the woman he loves slip away one pink-glowing moment at a time.
But Amari didn’t survive all this time by giving up. And Carla didn’t become Queen of Limbo by backing down from impossible choices.

Together, they’ll face vengeful spirits, corporate conspiracies, and fate itself. They’ll build weapons and cast spells. They’ll sacrifice everything to protect their spider children and the family they’ve chosen.
Because some loves are worth fighting for. Even when the battle is against destiny itself.

An extended epilogue filled with magic, sacrifice, and a love that refuses to break.
