A remarkable sensitive girl struggles to make friends in an impossible fifth-grade world filled with magical creatures only she can see.

In a small Indiana town, Meredith experiences whimsical within the mundane. Fireflies dance inside lampposts, flowers wave in greeting, and an opinionated beetle named Floss wreaks havoc on her life. No one believes her - not even her parents - but more pressing problems are at hand.

The widower neighbor, who is like her grandparent, won't leave his home. He has been jinxed, Meredith believes, by Billy, aka her bully. Desperate to free Mr. Dally, Meredith devises a plan. What can go wrong?

With Floss sabotaging her? Everything. The task may be more than she can handle alone.

Then Meredith meets Jax, a curious boy who claims to see her extraordinary friends. He agrees to help. Against her better judgement, Meredith leads him inside her fantastical world only to discover Jax has plans of his own.
