An unexpected friendship leads to thrilling exploits for a little girl and a tomato worm in The Silly Adventures of Petunia & Herman the Worm ($17.95, Book Baby LLC). The book evolved from a bedtime story author Sam Baker made up for his now-adult children when they were young. Children’s book authorship is Scottsdale nonagenarian Baker’s fifth career. Previously, the Mississippi native was an engineer, served in the United States Marine Corps, was an ensign in – and later director of – the National Geodetic Survey, and sold GPS systems.
