From the back cover. ZOMBIES ON A SPACESHIP! Chief Engineer Madison Whitehawk suspects foul play when a series of small anomalies occur aboard the ark ship Freedom. But Madison's fears are nothing compared to the impending disaster heading their way. As the team of scientists, engineers and crew take their precious colonist cargo towards New Earth a deadly parasite has found its way onboard. Soon Madison, Second Officer Crichton and colonist Syra Connor are fighting for their life's against trusted friends and former lovers. What is the parasite that changes the minds and behaviour of those it infects? And how can the crew of the Freedom destroy the darkness within? This short novel from the ever reliable Sam stone mixes science fiction with horror to good effect. The plot is a nice take on zombies and vampires set on a spacecraft. The characters are well created and the story is unsettlingly good fun. Sam writes well and I've enjoyed other books from her in the past and this one certainly doesn't disappoint. As a short novel the story cracks along and it ends with a swiftness a longer book would have been able to slow down but it's still works for me. Very good.
