Heidi Walker makes lists. She is careful and cautious. Heidi enjoys running, too. Bean is her brother. To say he is adventurous is an understatement. Their mother, Joy, has ... issues. Time and again, the trio tries to keep hope alive only to have it squashed. Learning to lean on each other through one adventure after another, like drinking Christmas tree bubble lights, trying to make a baby brother with some lemon seeds, and more, Heidi tells her story about surviving the adults in their lives. When Heidi is asked to hope once again, she is not sure she wants to take the chance.
