Ironically, Boudreau wrote most of her first novel in the "Real Mermaids series", Real Mermaids Don't Wear Toe Rings, on her feet. An avid walker, she stated "I find when you're on the move, it helps your thoughts be on the move, too." Boudreau married Gordon Clarke, a retired lieutenant and former President of the Royal Military Colleges Club of Canada. They have two daughters together, Charlotte and Marcelle. Although the family resides in Markham, Ontario presently, Boudraeu's "birthplace [of Petit de Grat] greatly influences the themes of [her] writing for children." Boudreau is known to be "...a compulsive walker, a chicklet wrangler and a lover of cheese and cheap chocolate." Authors that inspire Boudreau include Madeleine L’Engle, Louis Sachar, Katherine Paterson and Kate DiCamillo. She is also an active member of The Writers' Union of Canada.
