Dragon Tear

Eleven-year-old Jack Carter begins sixth grade at a new school. He's more intelligent than other kids his age, but his grades are far from perfect. Jack suffers from headaches and strange dreams, but he keeps these things secret, even from his mom. In the dreams, someone calls to him, but Jack doesn't know who or why.
An extra severe headache lands Jack in the hospital, which is when his life flips upside-down. He wakes wearing a strange necklace and receives a warning that he must escape the hospital immediately. The reality Jack knew has disappeared, replaced with a strange world of magic and dragons.
With no time to adjust, Jack is tasked with restoring the four towers that balance the universe. Using his intelligence and strength, Jack faces incredible obstacles he never could have imagined. Along the way, he discovers who he is and his true purpose, all while saving his home from certain destruction.
