If you haven’t yet bought a copy of the second edition of Positively False (why not?!), you might be in luck if you’re a US resident.
We are giving away 5 copies of the paperback (with free delivery) to every lucky 7th entrant who also follows our shiny new Twitter account: @immunityorguk
To enter, just click this link (your name and address will not be shared with us as Amazon.com are handling the specifics), and if you’re lucky you’ll have one of the best books of 2015 through your letterbox…
The draw ends on March 3. Spread the word.
