Broken Realms (The Chronicles of Mara Lantern, Book 1

Mara Lantern doesn’t believe in metaphysical powers and alternate realities. That's about to change. 

After a jetliner plunges into a river near Portland, Oregon, everyone survives. So why do crash investigators have a hangar full of bodies, one for each passenger except Mara? Before the plane goes down, she sees a boy running down the aisle carrying a blue light, chased by a girl who could be her clone. By trying to help, she unwittingly unleashes dozens of creatures that threaten her life, her family and everything she believes. To save them, she must embrace a power she cannot comprehend.
