What started as a prayer during a drive home from work has grown into a children's book series designed to get kids moving, reading and making healthier choices.

For David Norec, the idea came during one of the most difficult periods of his life after losing two siblings to diabetes.

Norec, a former teacher who grew up in the Rio Grande Valley, founded Fit-Lit, a company that combines literacy and exercise through interactive children's books designed to address obesity, diabetes and illiteracy among children.
