Because Parr didn’t have an itinerary for his travel, he promised to stay in touch regularly by texting and blogging. His tales interested family and friends, especially his 9-year-old cousin Destiny. Inspired by Destiny’s interest in his travels; their shared love of science; and the dearth of fun, smart books for young girls, Parr created the character and book series Sage Carrington: Eighth Grade Science Sleuth. The series features a young girl and two best friends who solve science mysteries while enjoying a wide range of cultural experiences.
