Hand Made Mage
Ghost, a young Criminal Guild thief, is ordered to rob an ancient crypt of a long dead Duke. He is caught grave robbing by an undead, insane Mage, with a twisted sense of humor. The Mage burns a set of rune engraved rings into Ghost's hand, and fingers. Unknown to Ghost these rings allow him to manipulate the four elements.
Returning to the Guild to report his failure, everyone thinks he has riches from the crypt, and they want it. While being held captive by the Criminal Guild, Ghost meets Prince Kade, the fourth son of the King, who has troubles of his own. Ghost uses his newfound powers to escape from the Guild saving the Prince in the process.
Spies from a foreign kingdom are trying to kill Prince Kade, and Ghost must keep them both alive, while helping Prince Kade raise an army to stop an invasion. Ghost finds out trust to soon given, is unwise and dangerous. He is learning people will do anything for gold and power. As Ghost's power grows, his enemies learn he is a far more deadly enemy than anything they have ever faced.
I loved this book. I couldn't stop reading it and stayed up so late I almost fell asleep at work the next day. I highly recommend it. I really really hope the author writes a sequel.
