Timothy Limpet feels out of place in the troll family - he likes things to be just so, and most trolls, frankly, don't. Tabitha Lumpit likes things to be loud, loopy and messy and she feels like a fish out of water in her very neat family. Sometimes they wonder if their families really see them for who they are, so when Timothy and Tabitha meet on the bridge they each decide the other's family is a better fit and swap places . . . with hilarious and touching results. Based around the time-honoured theme of home is where the heart is, this warm and witty story is a celebration of the individual and offers a valuable lesson on not judging others.
