Charlie Wilde can’t believe she has to move to hot, boring Arizona. Good-bye, deep-dish pizza, her best friend, and everything else she loves about Chicago. Hello, cacti around every corner, parents who spend all their time at their new jobs, and trying to fit in at a new school. It couldn’t get any worse.

Then one day Charlie finds a high-tech bracelet that looks just like the ones athletes use. There’s no sign as to where it came from, but she decides to wear it to soccer tryouts, thinking it’ll help give her an edge. And things start to look up when she makes the team and hits it off with another player.

But soon Charlie realizes she’s changing. She’s able to run across the field as fast as a cheetah and lift heavy objects as if she were as strong as an elephant—and that’s only the beginning. Charlie would be thrilled about her transformation if she had any idea how the bracelet works, but it didn’t come with instructions. So it’s up to her and her new friends to figure out what’s happening—and if there’s a way to control her incredible powers.

Charlie knew moving was going to completely change her life, but she never could have guessed how right she really was. . . .
