Imagine a disease: invisible, infiltrating. Everywhere. You cannot escape this virus. It will get you.
Unless you’re one of the lucky ones with immunity, the Death Flu will kill you; it’s only a question of when.
Though, perhaps, if you have immunity, that makes you one of the un-lucky ones. Your friends and family — those you so recently regarded as sorry victims of the disease — are now rising once again, your mindless, implacable enemies, forever hungering for your flesh.
As you pick your way through the broken remnants of a shattered country — always on the move, never safe — you soon realize that there is something to fear every bit as much as the pursuing zombies: the other survivors.

Nice blurb–you set up the situation and hook the reader.
Thanks very much.
I’m really keen to publish this novel. It has a character called Jack who is so capable of evil that I couldn’t take my eye of him; I had to keep on reading the manuscript in case he snuck up on me.
