Twelve-year-old Daisy and Ruby are totally inseparable. They've grown up together, and Daisy has always counted on having Ruby there to pave the way, encourage her to try new things, and to see the magic in the world. Then Ruby is killed in a tragic accident while on vacation, and Daisy's life is shattered.

Now Daisy finds herself having to face the big things in her life--like starting middle school and becoming a big sister--without her best friend. It's hard when you feel sad all the time. But thanks to new friends, new insights, and supportive family members, Daisy is able to see what life after Ruby can look like. And as she reaches beyond that to help repair the world around her, she is reminded that friendship is eternal, and that magic can be found in the presence of anyone who chooses to embrace it.
