Most writers research a little when writing fiction, despite the fact that they can make everything up if they feel like it! Linda Acaster is no exception, in fact as far as I'm concerned she's the Indiana Jones of novel writing - questing after facts as well as truth wherever it may lie, then presenting it to the reader like an artefact to a museum.
'Torc of Moonlight' was especially interesting for me because I studied at the university where some of the action takes place, but this time-slip thriller (what a genre!) is perfect for anyone who fancies reading something that boasts as much detail as it does action. And you never know, you might even learn something about history, mythology and geology on the way!
