Meet Isabel and Nicki Hoffman!

Girl Power decorative element

Isabel and Nicki Hoffman are nine-year-old fraternal twins growing up in Seattle, Washington. So while they share a May 22 birthday—of course they’re Gemini, the sign of the Twins!—that’s pretty much where the similarities end.

Isabel and Nicki's story

Daisy and alien head decorative element

 

It’s 1999 and Mom is working lots of hours at her tech job, making sure the computers don’t crash when the world rings in the year 2000. Dad? He’s keeping Mom—and everyone else in the neighborhood—caffeinated courtesy of his coffee shop, Coffeegarden.

As New Year’s Eve approaches, Nicki is increasingly worried about what will happen if the computers do crash: will the world really end like some people are saying? And Isabel feels like it is the end of the world when her best friends kick her out of their Millennium Dance routine. As always, the girls use their twintuition (their ability to guess what the other is thinking) to lift each other up by creating a countdown list of things to do before Y2K, so they can both face their fears and come out on the other side with confidence.
