“Lily and Maia is a highly engaging story which will energize an interest in STEM for all young people, but especially for girls who will be able to see themselves in Lily’s journey. I’m looking forward to sharing this wonderful resource with the thousands of the programs served by the National Girls Collaborative network.”

“As the mother of two elementary-aged girls who enjoy books with strong female protagonists, I appreciate that Lily is a confident and capable explorer. Readers will be inspired by Lily’s curiosity, enthusiasm for paleontology, and her deep interest in science. Lily and Maia…. A Dinosaur Adventure will encourage young readers to learn more about the world of paleontology and sets a great example for girls who are interested in science and nature.”

“The wonder and curiosity with which young people explore the natural world is reflected in Lily’s adventure with her new dinosaur friend, Maia. Young girls especially will be inspired by Lily’s confidence, creativity, and her excitement in doing research to discover truths about dinosaur lives. What’s more, the vibrant, engaging illustrations make it easy for young girls to relate to Lily and see themselves as scientists like her.”

“Lily shows young scientists, and young girls in particular, that they can make important discoveries about the world around them- all it takes is searching for the truth to a question!”

Lily and Maia is a delightful introduction to paleontology for kids. Many children are aspiring fossil-hunters and will likely be inspired by this story of a young student making discoveries in the field. I appreciate that the book introduces tools and practices of science, including making and recording observations and using evidence to draw conclusions. The young child in the story may even have made an observation that upends an argument made by an established scientist – a wonderful notion that will keep kids on their toes. The author’s clever device of allowing Lily to dream that she meets an actual dinosaur brings the story to life. I highly recommend this book for all families and schools with curious kids.

“Am I dreaming? Dinosaurs are extinct. There’s NO WAY we can be here together right now!”

Just like the young character Lily, students will get swept away in the magic of Maia the Maiasaurus. Author and world-famous paleontologist Dr. Jack Horner takes readers on a journey deep into the Badlands of Montana, with rich details and description at every turn. Watercolor illustrations by Grace Hattrup paint the canyons in vibrant, amber hues. Beware grown-ups! Your junior scientists will be wanting to pack their picks, rock hammers and chisels for a summer adventure finding fossils.

Thanks to Horner Science Group for sending a copy of #Lilyandmaia to me which I read last night. It is a page turner, as I followed with intrigue the adventure of Lily. I also learned some new things reading it, even as an adult, and a biologist not less. 😄

Lily is a very brave girl, and her passion with courage and determination as a young paleontologist literally jumps out from the pages. The narrative is effectively enhanced like a motion picture through the beautifully illustrated drawings, by Grace Hattrup, which children and the child-within-adult will resonate with instantly.

The story ends with a cliff hanger effect. I found myself turning all the pages to the end of the book and wondering if there is any indication of a continuation of the adventure n scientific exploration of Lily with her secret friend Maia.
Lily is a role model not just to girls, but boys as well; and also not just for children but for adults too! Happy reading!

Jack Horner ranks among the greatest dinosaur paleontologists of all time. He has also played an outsized role in popularizing the new science of dinosaurs, forever changing the way we look at these amazing ancient animals and inspiring many to pursue fossil-hunting careers.

With Lily and Maia, Horner taps into this vast experience to create a wonderful children’s book. Readers will head out into the field in search of dinosaur remains, and even set off on some time-traveling adventures! For the legions of young dinosaur lovers out there, here is a story guaranteed to spark imaginations!

Lily and Maia, written by legendary Montana paleontologist Jack Horner, and colorfully illustrated by Grace Hattrup, will capture the fertile imaginations of young children, especially those who love All-Things-Dinosaur. Lily, a budding young paleontologist, convinces her trusting parents that she be allowed to camp and explore Montana’s Badlands all by herself. Her parents agree, surprisingly, and had they not, Lily’s discovery of a baby Maiasaura dinosaur and her subsequent journey through chokecherries and a crack in a cave wall would never have happened. Or did it?

Whether read to a group of children in a library, bookstore, or campsite setting, or read by young readers themselves, Lily and Maia will make children want to travel to Montana to dig for dinosaurs.
