Bone Baron (Fated Touch Book 7) - Fated Touch, #7

Jane and her friends are both heroes and outlaws. Their notoriety forces them to hide in the wilds of the north in the land where Caius grew up. The serenity of the wide steppes somehow compliments the brash nature of Jane's dragon shifter. Unfortunately, the quiet peace they seek is dashed soon after their arrival with the news that not only does Caius have a younger brother, but he's in trouble.
One of the local leaders, Baron Volkov, has taken to his manor at the outer lands of the principality. They endeavor to rescue him, but find themselves surprised by a most unexpectedly warm greeting from the baron. However, all is not as it seems, as Jane's powers elude. Not all of the doors of the manor are open to them, and behind some of those locked portals lay terrible secrets. Ones that concern Caius, his curse, and his future.
Now Jane must save her beloved dragon shifter from the clutches of a dark evil intent on using him, even if it costs him his life.
