From the author of Frostborn comes book two in the acclaimed Thrones and Bones fantasy-adventure trilogy for fans of Lloyd Alexander and Brandon Mull.
Karn Korlundsson is a gamer, not a riddle solver. But in order to rescue his best friend, Thianna Frostborn, he will need to travel to the faraway city of Castlebriar (by wyvern), learn how to play a new board game called Charioteers (not a problem), decipher the riddle of the horn, and tangle with mysterious elves.
Meet Desstra. She's in training to join the Underhand - the elite agents of the dark elves. When she crosses paths with Karn, she is not all that she appears to be.
Everyone is chasing after the horn of Osius, an ancient artifact with the power to change the world. The lengths to which Karn will go in the name of friendship will be sorely tested. Who knew that solving a riddle could be so deadly?
