Death's Queen. In Deception's Shadow, #4

Death wants his queen back. After her two sisters are caught up by destiny's call, Lamarra Stonemantle is the only one left to play the role of dutiful noble daughter. A task she embraces in an effort to hide the dark magic living inside her own soul. Now that power is whispering its seductive promises again, telling her only a long dead king can complete her soul. That unknown being terrifies her, but when Lord Master Trensler orders his acolytes to capture Lamarra, she must flee her home.
To her dismay, she is rescued by tomb guards sent by her dead king. Lamarra soon learns her fate is just as terrible as she thought, but Dead King Soryn isn't anything like she feared. He's worse. Yet he's also gentle and kind and he knows a way to track and destroy the acolytes' evil god. But Lord Master Trensler has his own plans. If he cannot match power with the Dead King, then he will go back in time and eradicate Soryn before he ever has the chance to become the Dead King. There is one thing Trensler did not factor into his plan-Queen Lamarra and the protective instincts she feels towards her new king. Author's Note:In Deception's Shadow is a series best read in order for maximum enjoyment.
