The Girl Who Kissed a Lie (Otherworld, #0.5)

Before the enchantment breaks, Selkie thinks she's just an average teenage girl...

It's the beginning of summer vacation, and everyone at Selkie Stewart's Boston high school is excited. Except for Selkie, who sees herself standing at the edge of an abyss of Nothing To Do. Selkie doesn't want to spend her summer scouring the kitchen for gnomes with her crazy aunts or mooning over the enigmatic boy on Boston Common. So instead Selkie goes in search of a job. What she finds is a new best friend, a cute boy who might be more than he seems, and even more question about her mother and her past — and a sense that Selkie's adventures are just beginning.
