The Djinni: What You Wish Isn't Always What You Get: Night Terrors, Volume 1 (Unabridged‪)‬

Careful what you wish for...

Ken is an average student and a socially awkward teenager who is often the victim of pranks by the school bullies. The only thing that helps him escape his tedious life is his love for mobile games, so he spends hours and hours on his phone playing. 

Until one day he comes across an application that will transform his life: The Djinni. 

The boy now has the power to turn the tables, for The Djinni will grant him the wishes he desires most. However, Ken will soon come to understand his wishes always come with a price, and perhaps sometimes the price he has to pay is too high for his own benefit.
