Rebel Spring ( Falling Kingdoms #2) by Morgan Rhodes (v2)

Love, power, and magic collide with war in the second book of the Falling Kingdoms series

Auranos has fallen and the three kingdoms—Auranos, Limeros, and Paelsia—are now united as one country called Mytica. But still, magic beckons, and with it the chance to rule not just Mytica, but the world...

When the evil King Gaius announces that a road is to be built into the Forbidden Mountains, formally linking all of Mytica together, he sets off a chain of events that will forever change the face of this land, forcing Cleo the dethroned princess, Magnus the reluctant heir, Lucia the haunted sorceress, and Jonas the desperate rebel to take steps they never could have imagined.
