Bestselling author Jamie Kelly has been keeping diaries for years . . . and each one just gets funnier! But she has no idea that anyone is reading them. So please, please, please don't tell her. Something strange is happening at Mackerel Middle School. Even stranger than Jamie and Isabella becoming friends with Angeline. (Which is still really, really strange.) Jamie can suddenly and inexplicably understand the weirdest and most mysterious creatures around: Boys. And there's only one logical explanation --- superpowers.
