This is a splendidly entertaining novel about a teenage girl who gets taken over by a demon that turns out to be friendly, and confers on her all sorts of supernatural powers, which she uses to help protect Queen (Elizabeth I) and Country. Author John Lambshead is the father of two teenage daughters, and it is evident that his character Lucy is written from first-hand experience.
The novel is part fantasy, part history, and part science fiction. After a science fiction prologue introducing the demon (which I sort of skimmed the first time, but enjoyed on a second reading), the book really hits its stride when it lands in the Elizabethan era and we meet spymaster Walsingham, his secretary Simon Tunstall, Dr. John Dee, and of course Lucy. It is evident that Dr. Lambshead has extensive knowledge of this period and is deeply in love with it. There are lots of winning period details, such as when Tunstall cuts his breakfast with a "good Sheffield blade: and then dresses for the day according to his social rank. In many places the history seamlessly ellides into the fantasy in a most enjoyable way.
All the characters are deftly drawn, and the historical ones are very true to life: you'll feel you've had an audience with Elizabeth (and be grateful you didn't have to do it for real), you'll fall in love with Lucy (but, take a number), and you'll cheer on her sea captain beau William Hawkins (but you'll wish he wasn't such a chucklehead about women). There's lots of romping good action and plenty of humour.
Dr. Lambshead wisely inserted just enough historical background that readers need not have any prior knowledge of the period in order to follow along just fine. (Ignore the stupid Publishers' Weekly comment in this context: this is a fantasy novel written for an American audience, the background asides are necessary and not at all heavy-handed.)
Buy this book, read it, enjoy it, and let's hope for more soon. Bravo!
