Rushing to her home world to save a friend brought only heartache. Can Iliana now save Brandon? A desperate return to her world has left Iliana shaken, but a gut feeling that something's wrong in Brandon's world sends her riding hard for the Ivory School. When she arrives in Los Arboles, the campus is a smoking ruin and bodies litter the grounds. She finds a few survivors and learns Brandon-and others from the school-have been kidnapped...by an enemy everyone thought was dead. The only way to rescue Brandon is to use the skills she honed at his school. But she has no way of knowing if he survived the attack or if he even wants her rescue, and it's not like she can text or track him with GPS. With the help of the only uninjured student, she heads back to the Karobis Desert, hoping she's not too late to save everything that matters to her in this-or any-world. The Karobis Calls is the fourth story and dramatic conclusion to the four-part serial recounting Iliana's journey along the Ivory Road.
