Where Home Lies - Rebel Mage, #3

Once an exile, Matthias returns to lead his home Enclave and settles into a new life with his beloved Solomon. Struggling with his new role and responsibilities toward the new town of Sanctuary and the people who had once rejected him, he knows that the relative peace he's found is temporary-the forces that destroyed Haven are still out there, and he knows that they'll come looking for him. Until they do, there are alliances to make, mouths to feed, and people who look to him to protect them.
Then tragedy strikes, sending Matthias, Solomon and Tam out once more, seeking answers in the forbidden north; answers that may lead to new beginnings, or to the end of everything they've ever known.
