I Wish I Weren't a Djinni

The Cotton Candy Quintet Book Prequel

All she wished for was freedom. 
 
After being trapped inside her bottle for so long she has forgotten her own name, a djinni is summoned by a young man who needs his wishes to come true as much as hers. 
 
The hardest part is proving to him that she has the power to grant them. He simply has to believe her enough to ask.
