Gabby and Evy love to have fun with their parents, they do all sorts of activities. One day Mommy is diagnosed with an invisible illness, and it is hard for the children to understand that she is sick because she does not look sick. The children learn that while mom may be in the hospital sick it does not mean that she loves them any less. Together they learn to deal with Mom's new illness, and still enjoy the fun and games they did before she was in the hospital.

This is a good book to explain invisible illnesses to children. It is meant to be a conversation starter, giving them the opportunity to understand things that their loved ones are going through.
