Web of the Timeweavers (Spellheart #8)

Theo's old friends are just out of reach, but it's past time he went looking for them.

With the world safe and the Hearthwood Clan prospering more than ever, Theo finally has both the opportunity and the power to go looking for Sam and Dean, who went missing hundreds of years ago. There's much to do at home, but once his affairs are settled, Theo plans to chase their trail and figure out what happened to them so that he can bring them home.
