“Sharon Duke Estroff is growing her brand’s recognition through books. Estroff, who has previously written a parenting book as well as numerous articles for parenting and other magazines, has turned her talents to co-writing a series of children’s fiction books called Challenge Island STEAM adventures. The first book, Bridge to Sharktooth Island, published in November, was ranked a No. 1 New Release on Amazon and received numerous critical accolades. The book’s success has already helped franchisees reach more parents and kids and schedule more of their STEAM enrichment class packages with school districts.” – Entrepreneur Magazine, March 2022
