Kayla McHenry's sweet sixteen sucks! Her dad left, her grades dropped, and her BFF is dating the boy Kayla's secretly loved for years. Blowing out her candles, Kayla thinks: I wish my birthday wishes actually came true. Because they never freakin' do. Kayla wakes the next day to a life-sized, bright pink My Little Pony outside her window. Then a year's supply of gumballs arrives. A boy named Ken with a disturbing resemblance to the doll of the same name stalks her. As the ghosts of Kayla's wishes-past appear, they take her on a wild ride...but they must stop. Because when she was fifteen? She wished Ben Mackenzie would kiss her. And Ben is her best friend's boyfriend.
