Sunshine coauthored her newest book, Rabbit Rabbit, with Dori Hillestad Butler. It publishes April 15, 2025. Here's the scoop:

Twelve-year-olds Alice and Bee are practically strangers when their grandparents' anniversary party reunites their estranged families and ignites their own fast friendship.

But their reunion doesn't last long. Bee's mother and grandfather are dead set on keeping the liberal Seattle faction of the family away from the conservative Minnesota crew. "It's complicated," the adults tell them over and over (and over!) again. What happened all those years ago, and why did it tear their family apart?

Just when they've started to make progress on figuring out the big family secret, the COVID pandemic strikes. Bee and Alice watch as the world shuts down and their loved ones grow further divided along their fractured lines. Somehow, it's up to the twelve-year-olds to clean up the mess the adults have made.

This powerful, timely story cuts deep, touching on recent historic events and intimate family details alike. Readers will fall headfirst for Alice and Bee as the unforgettable tweens make space for their friendship and shifting identities while standing up to their family with all the love and grace they can muster.
