Penny, the Engineering Tail of the Fourth Little Pig

Kimberly Derting is the author of the Cece Loves Science series, the Body Finder series, the Pledge trilogy, and the Taking series. She lives in the Pacific Northwest, where the gloomy weather is ideal for writing anything dark and creepy. Her three beautiful (and often mouthy) children serve as an endless source of inspiration and frequently find things they say buried in the pages of their mother's books.

Shelli R. Johannes is coauthor of nine books in the Loves Science picture book series, including Cece Loves Science, as well as the author of Theo Thesaurus and Shine Like a Unicorn. ​ Shelli never warmed up to creepy-crawly bugs, but she always loved zoology and biology. In fact, she can often be found on highways and country roads saving strays and other jaywalking critters or volunteering with animal conservation groups like the Atlanta Zoo, the Dolphin Project, and Bosley's puppy orphanage. After earning a master's in marketing and working in corporate America as an SVP, Shelli traded out her heels and suits for flip-flops and jeans so she could follow her passion for writing. She lives in Atlanta, Georgia, with her own pack: a British husband, two kids, one bird, one fish, and two crazy-haired doodles who hate veggies.
