Reading it has made me want to dig out my old copies of boarding school stories like Elinor Brent-Dyer's Chalet School books, and time travel books like Charlotte Sometimes by Penelope Farmer and Alison Uttley's A Traveller in Time.
Other boarding school stories that readers might enjoy include [[First Term at Silver Spires (School Friends) by Anne Ann Bryant]] and Jill Murphy's [[Worst Witch to the Rescue by Jill Murphy|Worst Witch to the Rescue]] (and the five previous books in that series).
Other time travel stories include [[The Queen Must Die by K A S Quinn]] and [[Timecatcher by Marie Louise Fitzpatrick]].
