An exciting read with a really lovely premise, that the extraordinary skill and speed of ninjas come from the fact that they are all vampires. This blending of genres really works. It’s officially a young adult’s read but it has great cross-over appeal. Fast, fun, full of fights, thrills and highly likeable characters, I can’t wait for the next one. Comparison: Ursula Le Guin, James Patterson (Maximum Ride series), Lian Hearn (Across the Nightingale Floor series).
