Early years

Miscellaneous work
GrandPré has illustrated all of the American editions of the Harry Potter novels. She was one of the few people who were able to read the Harry Potter books before they were released to the general public. When she received each new book, she read the story through once, highlighting descriptions that she felt would do well as an illustration. She then created various sketches as ideas for the cover and chapter art, before sending her favorites to the editors to decide which should appear in the final publication. GrandPré is very careful to make sure that her illustrations give hints as to what will happen in each chapter or within the book, without making it very obvious where the plot is headed. GrandPré does not collaborate with J.K. Rowling at all.
In Harry Potter and the Order of the Phoenix, GrandPré depicts the character Severus Snape as a balding man with a goatee, even though he is constantly described as hook-nosed, with pale skin, and greasy, shoulder-length black hair.

Harry Potter series
In addition to the Harry Potter series, she has illustrated picture books including Pockets, Chin Yu Min and the Ginger Cat, Vegetables Go to Bed, The Thread of Life, Swing Around the Sun, The Sea Chest, and Sweep Dreams. She also illustrated Plum, and Henry and Pawl and the Round Yellow Ball, which was co-written by her husband, Tom Casmer.

Recognition
GrandPré has recently begun creating art for herself instead of for an assignment. She has donated several pieces to The Wellness Community of Southwest Florida, a non-profit organization providing support for people with cancer.
