Changeling

Tinsley Scott isn't having the greatest year. Her boyfriend refuses to let her meet his family, her mother is convinced she's on drugs, and her little sister's meddling has hit an all-time high.

When she tries to run away from her problems, though, they only get worse. One accidental plunge through a puddle later and she finds herself in the mysterious Faewyld. There, she learns that she's a changeling, the spirit of a dead Fae who took refuge in a mortal body. Now she has a whole other world she can escape to.

Perfect, right?

But being a long-lost fairy princess has its own set of problems. War, magic, betrayal... Death. Suddenly, passing calculus doesn't seem like such a big deal.
