Thief

THIEF: Eternal Wardens
He was Vexis Thorne's deadliest weapon. Now he's the man determined to destroy him.
Kael Vireon has spent his life serving power. As the right hand of Vexis Thorne, he enforced VIP-D's will with ruthless precision. But power corrupts-and Vexis isn't just corrupt, he's chaos wrapped in human skin. Every order Kael follows leaves another scar on his soul.
Until the day he vanishes.
Reborn from the ashes as Hades, Kael leads a clandestine network of operatives waging war in the shadows. He's stolen secrets, sabotaged supply lines, and built a resistance meant to burn VIP-D to the ground. But when the chance comes to steal Vexis's most prized possession-his chosen bride-Hades can't resist.
There's just one problem.
Odessa Adrian isn't the delicate, terrified pawn he expected. She's been playing her own long game, infiltrating VIP-D with one goal: assassinate Vexis Thorne. Furious at Hades for blowing her cover, Odessa has no intention of being anyone's prize.
Now hunted by VIP-D and forced into a fragile alliance, Kael and Odessa must navigate a deadly game of lies, seduction, and betrayal. Their only hope of survival-and revenge-lies in each other's hands.
But in a world where trust is deadly and love is a liability...
Who's really stealing from whom?
