Vega Sloane's brother, Will, and best friend, Liv, have been taken, and it's up to her to bring them back to the safety of their own world. But what seems like a simple rescue mission quickly turns into something far more perilous than Vega could ever have imagined. Trapped in a place where nothing is quite as it seems, she can't help but wonder if she'll ever find her way back to the Academy, to the strange new friends she's met...and to the mysterious boy who has captured her heart. In her first encounter with the Usurper Queen, Vega learns that she's not the only one with family secrets. But perhaps some secrets are best left unsaid.Seeker's Quest is the second book in the Seeker's World Series.
