Outlaw's Vengeance - Gail Z. Martin

Buddy flick epic fantasy! The fifth in the Assassins of Landria series from the awardwinning, bestselling author of Scourge: A Novel of Darkhurst and The Chronicles of The Necromancer.
A secret heir. A kingdom in crisis. A magic-fueled blight with horrifying consequences. And an unlikely band of outlaws and misfits who are Landria's only hope against the powerful, malicious Witch Lord.
Rule-breaking, unconventional assassins Joel "Ridge" Breckenridge and Garrett "Rett" Kennar team up with rogue spy Kane and the imprisoned, notorious mage of Rune Keep to save their kingdom, despite the bounty on their heads. When Rett's mind-scarred magic
sends him to a place that exists outside of space and time, he discovers that the solution to Landria's succession to the throne is hidden in a magical safe house.
But the spell that maintained the monastery is crumbling, and the Witch Lord is intent on stopping its secrets from becoming known. Meanwhile, provocateurs rampage in the borderlands trying to start a war, and a witch with a deadly grudge conjures a terrifying
infestation that could destroy everything. It's up to Ridge, Rett, Henri, and their friends to stop the threat and protect the throne while they evade capture on the kingdom's "most wanted" list!
Amid a web of betrayals and intrigue, can a group of outlaws and exiles stop a mage-sent plague, fend off a predatory neighboring kingdom, and protect Landria's best hope for a peaceful succession?
Outlaw's Vengeance is an action-packed epic adventure filled with loyal friends, honorable fugitives, secret sanctuaries, hidden magic, and unexpected explosions.
