"Funke follows her foray into YA (Reckless) with a simultaneously creepy and romantic middle-grade ghost story that will please her legions of younger fans. Despite the book's length, the story moves quickly, filled with daring midnight expeditions and close calls with death."--Publisher's Weekly
"Funke's consummate way with setting, well interpreted in Offermann's looming illustrations, brings the medieval English town (and all of its ghosts) to life, from the sprawling boarding school campus to the echoes-of-the-past cathedral and eerie cemetery grounds; a side jaunt to Stonehenge even adds some levity. Appended notes discuss Funke's inspiration for the story and provide history about the real-life people and places."--Horn Book
"Historic details about the real Hartgill, Longspee and Stourton are deftly woven into a ripping good story. It's told with self-effacing humor from the perspective of an awkward boy who emerges as honorable and brave as the ghost knight and the contemporary girl he befriends. Black-and-white illustrations add to the Tudor atmosphere and drama. Sword-swinging ghosts will haunt readers of this droll, harrowing and historically grounded ghost story."--Kirkus
