The Spirit Mage — Layton Green

Valjean thought about how impossible it seemed that there was another world out there from which he had narrowly escaped. A world of manticores and cave fiends, magic swords and potions, spirit mages and necromancers. Wizard-monks who could shatter walls with their fists, a city of colored spires so beautiful it took his breath away . . . and a world in which Val's brothers were still trapped. Desperate to help his brothers, high-powered attorney Val Blackwood manages to find a way to return to the world of Urfe. After landing in the dangerous underbelly of New Victoria, he concludes that the only way to find Will and Caleb is to enroll in the Abbey -- the school for wizards -- and somehow gain access to a portal called the Pool of Souls. Yet to succeed, he not only has to pass the entrance exam and survive the rigors of the school, considered the most demanding in all the Realm, but also avoid a lethal assassin targeting students. As Val struggles to survive, his brothers undergo an even deadlier trial. Reeling from the loss of Mala, an adventuress lost in the mysterious Place Between Worlds, Will and Caleb and Yasmina are captured by slavers and taken to the mines beneath Fellengard Mountain. Even if they manage to escape, a feat no one has ever accomplished, they must still find their way out of the vast and untamed caverns of the Darklands. A place even the wizards fear. Trapped in a land of dreams and nightmares, the brothers must somehow stay alive and learn to adapt to their new surroundings -- or risk losing their home world forever.
