Banished - The Riddled Stone, #1

Haunted by dreams. On a quest for answers. Christopher Fredrico liked the quiet life of a scholar-in-training. Plenty of spare time to spend with his friends. But the night Crown Prince Tyler came to dinner, everything changed. Falsely accused of stealing a magical artifact and banished under threat of death, Chris leaves the only home he knows. But as he and his friends travel towards the coast, they find a riddle that may save a kingdom - or cost them their lives.
