Taken by the Creatures on the Roof

"The boy leaned in "Just breath, princess", he whispered in her ear."
"Elizabeth's head was pounding, she needed air badly but she hated to be beaten by this boy. Her body was reeling now, she opened her mouth and gasped through the cloth. Her vision blurred and she felt her senses going numb. She felt her body giving into the blackness, but not before she pulled her knee up with the last of her strength and connected with a rather sensitive area."

The creatures will come get you when you turn 16, that's what Elizabeth has always been told. She never wanted to believe it, it was absurd. But when had anything in her life been normal, she lives in a city called Canterbury which is ruled over by the all powerful Queen Ursula. The city was her whole life, quite literally. It is surrounded by impossibly high walls. Some people were let out but only a trusted few. It was a prison, but nobody dared say that incase the Queen heard. Nothing came in and nothing came out. Well, the creatures came in. Elizabeth had never seen them but she had heard stories. Stories of flying pirate ships and horrible half human creatures stalking into homes at night and taking children who were old enough. She had convinced herself that they were not real, that is until her best friend was taken by them. Now she's determined to do anything it takes to get her back even if that means letting herself get taken by the creatures on the roof.

Ps. this will not be a dark story, definitely going to have a happy ending + romance!!
