The first book in The Dreamer Chronicles Trilogy is Sarina’s Nightmare [Out Now!].
This is the blurb that you will find on the back of the book …
She is hopeless at maths and science, and the Principal has made it clear that unless she passes the next maths assessment, she will not be allowed to continue her beloved art studies, and he will prevent her from entering the highly coveted ‘National Young Artists Breakthrough Competition’.
To add to her woes, a string of increasingly disturbing dreams transport her into a parallel world, and when she responds to a cry for help from the other world’s only remaining boy, a deaf-mute, she unexpectedly encounters dark magic.
To help him, she must battle a menacing sorcerer and a sadistic bird-like creature—and soon discovers she has hidden powers connected to her artistic talents.
The strange dreams put her maths results in jeopardy and turn her world upside-down. Suffering constant put-downs by the annoying school genius, Sarina struggles to find a way to rise above her challenges, until one day it all goes bad—and her dreams become her worst nightmare.
