"Outside of the Realm, everything is unknown."

Having paid a high price to pass through the Border, the Four depart the only lands they've ever known. They're faced with immediate problems and unknown dangers as they begin the perilous journey toward the fabled city of New York.

As they travel, Leora struggles to hone her powers, Roland and Aurora attempt to explore their new romantic relationship, and Leopold battles with his inner demons.

Meanwhile, all is not right within the Realm. The young sovereign continues to wield his new powers erratically, threatening the lives of every citizen. Now, several members of the gentry must navigate through the chaos to protect their homes and families.

Can the Four survive their journey? And if they do, will there be a Realm for them to return to?

Set in the far distant future, Test of the Four is the second book in The Serrulata Saga.
