Bob Williams (PopPop) and his grandson Jackson Schwarz both love writing stories. Besides the joy of creating stories together, Jackson and PopPop enjoy exploring and learning about God's creation. The two authors agree that God makes Himself clear to everyone through His creation. One example of God's creation is found flying high above the north Texas ranch where the Cousin Series takes place. For decades now, Harold the hawk has been flying high above their Texas property saving lives and providing insight into God's watchful eye and hand protecting and blessing all who love Him. Jackson, the co-writer of this latest Harold the Hawk adventure story, is in second grade in Round Rock, Texas. He loves reading and learning about everything but mostly history. He also loves his four siblings Addie, Maggie, Asher, and Gavin, his parents, and his many cousins.

Bob has been teaching English and history for over forty years in both public and private high schools. Bob believes that getting to write for and with his eleven grandchildren about Harold the Hawk is one of the greatest blessings of his life.
