Sixteen-year-old Jensen Meadows hands out tall tales like a vending machine. After all, with a con-artist for a big sister, she knows the value of a well executed lie. But when she overhears a murder confession at school and is abandoned by her sister, Jensen learns three new things: Drinking Red Bull isn't the only way to get wings: The faerie realm is real, and it still hasn't gotten over King Arthur's death. Shimmerspell, the power to move between the mortal and faerie realms, is lost. And somehow, her sister is tied to it all. With the help of a few teenage light-elves, Jensen searches for the truth in a sea of lies and begins to suspect that her whole life has been the tallest tale of them all.
