Hm, this was another extremely linear book that didn't really grip the imagination the way some of the others do. For starters, we're returning (yet again) to the world of The Moors, which we've already explored a fair amount in book 2. We don't really have any new characters, and there isn't really any character growth; it's a pretty linear story of "thing happens, react to the things in a straight line from A to B till the end of the book as everything falls into place". It's not bad, it's just predictable, and in the unpredictable worlds of the Wayward Children that falls a little flat.

Also I gotta say, for a place that has "No Quests" posted on the door, Eleanor West's Home for Wayward Children sure consistently fails to enforce that!
