Some lives are bigger than one reality. Because they have to be. The day Mara Lantern meets herself, her life gets bigger.
When she meets her brother from an alternate universe, it becomes more complicated.
And when her new mentor says creatures from other realms are invading this world, she thinks it’s absurd. Until he explodes into a cloud of dust and reassembles himself. That makes her doubt.
Then he says only she can stop the invaders. That makes her afraid.
