Dreamer: The Activation of Makeba, by Tanya Junghans

Thando Weber is a half South African and half Swiss nerdy girl with hopes of going to the best university in  Switzerland like her father did. She is also the last surviving  descendant of the Watchers of Realms, a powerful race of  light beings who watch over the Milky Way galaxy. Her  mission is to find her lower-self, and her higher-self to  complete her triad, so that she may bond with them and  be the next Dreamer – an interdimensional traveller and  protector of the Earth Realm.  

Tortured by the transformation of moving from human  to Dreamer, Thando hallucinates, sleepwalks, and  suffers sleep deprivation, which destroys her dreams of  tertiary education. On one mundane high school day, she  loses consciousness and plunges into a coma, not from  exhaustion but because she encounters her lower-self and  higher-self simultaneously.  

She starts her training to be a Dreamer, experiences challenges and travels through South Africa to find ways  to release her latent superpowers. As she trains, the Kryona  terrorises people around her to get to her. On her journeys  through South Africa, she meets powerful creatures of old,  ancient water spirits and primordial dragons who help her  with her training. She is guided to traditional healers to  assist her and comes across other traditional healers who  betray her due to influence from the Kryona. Through her  adventures, she learns about her mother’s Zulu culture and  inches closer to her goal, but it is not enough.
