A young adult sci-fi writer
who is actually good.
Gimmy A Kiss
The Last Vampire
Remeber Me I and II
And many more
His stories are very captivating and usually have a weird "YouAreNotWhoYouThinkYouAre" twist.
I was addicted to his stuff like crack when I was in 7th and 8th grade.
He also written several adult novels like Sati and Seasons Of Passage about vampires from Mars. But I am not particulary too impressed with those.
