Twelve-year-old Brendan, his twin brother, Nick, and their older sister, Ami, are struggling to cope with their father's recent death and their family's move to the country. When Ami discovers a hoofprint in the woods, she claims it belongs to a unicorn. Nick is dismissive of her plan to capture it, but Brendan feels drawn into Ami's imaginary world that includes a dangerous, nighttime journey to spy on an "ogre." Bulletin of the Center for Children's Books says, "Welch's writing is rich with detail . . ." VOYA calls it ." . . true to life . . ." The book was shortlisted for the Prairie Pasque Award.
