Robin D. Owens - Echoes in the Dark

The planet is dying, slowly being drained by an alien Dark, and only one last, desperate plan can save it. Deep in another dimension, a disillusioned young singer is summoned as Lladrana's last hope. Uncertain of her future, unaware of her extraordinary magical talent, Jikata will be the sixth and final outsider–Exotique–to step through a dangerous portal of prophesy and magic.Survival will require her to forge closer friendships than she has ever known. The price of those bonds will threaten the very fate of Lladrana: a world where music holds the key to an ancient mystery–and six women will wage the ultimate battle against the forces of Dark.
