Calpurnia Virginia Tate is eleven years old in 1899 when she wonders why the yellow grasshoppers in her Texas backyard are so much bigger than the green ones. With a little help from her notoriously cantankerous grandfather, an avid naturalist, she figures out that the green grasshoppers are easier to see against the yellow grass, so they are eaten before they can get any larger. As Callie explores the natural world around her, she develops a close relationship with her grandfather, navigates the dangers of living with six brothers, and comes up against just what it means to be a girl at the turn of the century.
Author Jacqueline Kelly deftly brings Callie and her family to life, capturing a year of growing up with unique sensitivity and a wry wit.

Jacqueline Kelly won the Newbery Honor for The Evolution of Calpurnia Tate, her first book. She was born in New Zealand and raised in Canada, in the dense rainforests of Vancouver Island. Her family then moved to El Paso, Texas, and Kelly attended college in El Paso, then went on to medical school in Galveston. After practicing medicine for many years, she went to law school at the University of Texas, and after several years of law practice, realized she wanted to write fiction. Her first story was published in the Mississippi Review in 2001. She now makes her home with her husband and various cats and dogs in Austin and Fentress, Texas.

“The Evolution of Calpurnia Tate" is the most delightful historical novel for tweens in many, many years. …Callie's struggles to find a place in the world where she'll be encouraged in the gawky joys of intellectual curiosity are fresh, funny, and poignant today.” —The New Yorker, "Book Bench" section
“In her debut novel, Jacqueline Kelly brings to vivid life a boisterous small-town family at the dawn of a new century. And she especially shines in her depiction of the natural world that so intrigues Callie… Readers will want to crank up the A.C. before cracking the cover, though. That first chapter packs a lot of summer heat.” —The Washington Post
“Each chapter of this winning…novel opens with a quotation from ‘On the Origin of Species'--a forbidden book that her own grandfather turns out to have hidden away. Together they study Darwin's masterpiece, leading to a revolution in Callie's ideas of what she might accomplish on her own.” —New York Times Book Review
“Callie's transformation into an adult and her unexpected bravery make for an exciting and enjoyable read. Kelly's rich images and setting, believable relationships and a touch of magic take this story far.” —Publishers Weekly, Starred Review
“Interwoven with the scientific theme are threads of daily life in a large family--the bonds with siblings, the conversations overheard, the unspoken understandings and misunderstandings--all told with wry humor and a sharp eye for details that bring the characters and the setting to life. The eye-catching jacket art, which silhouettes Callie and images from nature against a yellow background, is true to the period and the story. Many readers will hope for a sequel to this engaging, satisfying first novel.” —Booklist, Starred Review
“Readers will finish this witty, deftly crafted debut novel rooting for "Callie Vee" and wishing they knew what kind of adult she would become.” —Kirkus, Starred Review
“A charming and inventive story of a child struggling to find her identity at the turn of the 20th century… there's no uncertainty over the achievement of Kelly's debut novel.” —School Library Journal, Starred Review
“Narrator Calpurnia's voice is fresh and convincing, and Granddaddy is that favorite relative most readers would love to claim as their own. Historical fiction fans are in for a treat.” — The Bulletin of the Center for Children's Books
“Kelly, without anachronism, has created a memorable, warm, spirited young woman who's refreshingly ahead of her time.” —The Horn Book Review
“That rare book that will appeal to child and adult alike.” —Austin American-Statesman
“Introduces a turn-of-the-20th-century heroine for modern times.” —Shelf Awareness
