This book is based on the true story of a little girl named Grace and her grandmother, whom she calls G-maw. The dandelion in the story symbolizes the hopes and dreams that G-maw has for Grace and represents the bond and unconditional love between a grandmother and her grandchild, a bond and love that she will never forget.

Wish begins in a field where a little girl named Grace discovers the wonders of dandelions when her G-maw tells her of when she was a little girl and how she used to make wishes by blowing off the seeds of the dandelions. The story continues as G-maw tells Grace about the wishes she has for her in life. Grace can't stop thinking about all her G-maw told her and is in awe of what she has learned. The story ends with Grace thanking God for dandelions as she goes back to the field and thinks about her G-maw and all that she's learned.
