I don't know if this was a dream or not, but I swear around 5-6 years ago, I read a book about a young girl who possibly grew up in a circus, and one day she meets a boy (I think he was apart of the crowd?), they fall in love eventually and I swear there was also some supernatural aspect to it, monsters chase them at night?
EDIT: Despite my horrific description, many gave some suggestions, which I am entirely grateful for! I ended up finding the book, it was Freeks by Amanda Hocking.
Description: In a world of magical visions and pyrokinesis, Mara just wants to have a normal life. But is that possible?
Mara has become used to the extraordinary. Roaming from place to place with Gideon Davorin’s Traveling Carnival, she longs for an ordinary life where no one has the ability to levitate or predict the future.
She gets her chance when the struggling sideshow sets up camp in the small town of Caudry and she meets a gorgeous local guy named Gabe. But before long, Mara realizes there’s a dark presence lurking in the town that’s threatening the lives of her friends. She has seven days to take control of a power she didn’t know she had in order to save everyone she cares about—and change the future forever.
