Working Under the Warlord - Rocky Royal Romance, #6

What happens to a magic user when the magic starts using him?  Though he doesn't look it, the Warlord-in-Chief of Gratha is so old, he's forgotten the name his mother gave him. His mind cracking under the burden of the magic causes plenty of problems, but if the warlords knew, all Jersey would break loose. Even if he trusted his little apprentice with his secret (and his heart), there's nothing Frieda could do to help him...there's nothing anyone can do. Frieda didn't ask to be in this position.
Everyone else is scared stiff of the big, bad Warlord, but after years together, she's becoming more his equal every day. She's not disloyal; she'd never betray him. But she's not going to let him keep her at arms' length anymore...not when she finds out there's more at stake than he's let on.  He knows more about magic than anyone alive, but he's still clueless when it comes to love. Good thing his apprentice is ready to school him.  Working Under the Warlord is a standalone novel and the sixth installment in the sweet Rocky Royals Romance series.
It contains no open-door sex scenes, mild cursing, and a happily ever after. Content warning: this book contains a severely depressed main character, discussion of suicide and mental illness, and the death of an adult child.
