Today, the UK paperback of Apocalypse Cow, winner of the inaugural Terry Pratchett Prize, goes on sale. To mark this occasion of global import, I am giving away two signed and personalized copies, which I will post to anywhere in the world.

To enter the competition, simply answer the question below and post your response either as a comment on this blog, as a message to @MichaelLogan on Twitter, or as a comment on my Facebook author page.

The question is: If you were attacked by a zombie cow, what method and/or weapon would you employ to defend yourself?

The two funniest, and punniest, answers will win the books. If you lose, don’t worry: it’s on sale in all the usual places, priced at around six quid.

The competition will run until the end of Monday 13 May, and winners will be announced the day after. I will then arrange to get your home addresses privately, as we don’t want your online stalkers to find out where you live.

As to why you should want to win a book about zombie cows, here is what the critics think:

‘Apocalypse Cow made me snort with laughter’ – Terry Pratchett

‘”This clever and very funny twist on the traditional zombie novel is exceedingly well executed (it approaches but never quite steps into parody territory), and it ends with a scene that pretty much demands a sequel. Great stuff for horror and fantasy fans”‘ – Booklist (Starred Review)

‘A comic, blood-soaked romp through the UK, at times a hilarious social satire, and at others an action-packed gore fest, sure to please fans of the traditional zombie story…an accomplished novel by a promising writer’ – Press Association

‘Logan has a flair for unique description … and for painting a mental picture almost photographic in its clarity. An impressive start for an author who’s going places’ – Publishers Weekly

‘Michael Logan gives us a fast-paced dark comedy stuffed with violence, sprinkled with sex, reminiscent of Tom Sharpe, including witty lines and observations that are Pratchett-esque in their pointiness’ – Sunday Express

‘Ploughs the same furrows as Shaun of the Dead, wonderfully parodying the zombie and survival horror genre, but at the same time paying homage to it…worthy of a place amongst the best apocalyptic fiction…eminently readable, brilliantly written and side-splitting funny’ – Bookgeeks.co.uk

‘Logan manages to find a great balance between the dark and disturbing and the quirky and hilarious, all the while intermingling plotlines like a seasoned pro’ – Rue Morgue

‘This is one of the funniest zombie books I’ve ever read. Michael Logan has created a great new entry in the genre, and promises to be a must-read author’ – Night Owl Reviews

‘Michael Logan’s black comedy is an absurd yet utterly addictive read’ – Stylist Magazine
