Jade's life hasn't exactly been normal lately, especially since her dad's cancer diagnosis. Jade wishes her family could leave their no-name town in Colorado already--everybody else does sooner or later, including every best friend Jade's ever had. So she makes one up. In the pages of her notebook, she writes all about Zoe--the most amazing best friend anyone could dream of.

But when pretend Zoe appears in real life thanks to a magical experiment gone right, Jade isn't so sure if she likes sharing her imaginary friend with the real world. To keep her best friend (and even make some new ones), Jade learns how to cope with jealousy, that friends should let friends be true to themselves, and that maybe the perfect best friend doesn't exist after all.
