Barrier — Mary Victoria Johnson

Is it braver to trust your enemy, or to stand alone? She didn't mean to escape from Boundary. Yet, somehow, she did. Now, thrust into an unfamiliar and dangerous world, the young woman written off as a weak link must untangle the mystery of her past and find a way to rescue those still trapped within Boundary, while battling her own doubts and troubled past. But time is quickly running out and she has two choices: put her trust in an old enemy, or find herself completely alone...both are equally terrifying. Barrier is the second book in The Other Horizons Trilogy by teenage author Mary Victoria Johnson. The first Boundary is also available from Lodestone Books.
