Celia and the Wolf

Winner, 2014 Lyra Award for Juvenile Fiction from Bookstore Without Borders.
"A thrilling adventure with a fiery, engaging heroine you will not want to take your eyes off for a second!" - Ammi-Joan Paquette, author of Rules for Ghosting.
The year is 1806. Fourteen-year-old Celia Ashleigh is impatient to become a Deputy of the Crown, like all the other shapeshifting firstborn Ashleighs. When a very handsome French boy asks for her father€s help in rescuing his abducted sister, she doesn€t tell him her father€s away€“she takes the mission herself. But Remy Broussard hadn€t told her he and his sister are werewolves, nor that they€re being hunted by the dangerous Guardian of La Cluse. The Guardian€s plan is to have frightened villagers kill Remy€s little sister on the night Lilette €œchanges€ for the first time--the night before All Saints Day.
When a gypsy girl (who can turn invisible) joins Celia and Remy, Celia realizes that, for the first time, she has friends who are €œgifted€ just like her. But despite her enthusiasm and good intentions, and their help, she makes several crucial mistakes that jeopardize both her mission and Remy€s family.
As she comes closer to finding Lilette, Celia realizes The Guardian is actually insane with hatred€¦ and his hatred extends to anyone who is not completely human. Like Celia.
