The Amber Revenant - The Red Wraith, #3

Naysin's power is waning. The world knows him as the Red Wraith, an infamous shaman capable of eradicating plagues and ruining armies. But he spent the bulk of his magic atop the earthen pyramid of Saint's Summit. Now his mother is missing, and the Amber Revenant-another sorcerer with outsized potency-has hijacked the weather and delayed the spring. Naysin can't stand against the Revenant directly or find his mother on his own.
His allies don't always inspire confidence either: one of them is a teenage orphan; another is a cantankerous seagull. They have their talents, though. And Naysin still has his-for now. If he acts quickly, their combined strength might be enough. If he doesn't .Then the Revenant will supplant the Wraith. And his mother will never escape her fate.
