Half of a Yellow Sun website

Above is the half-page advert for Chimamanda Ngozi Adichie's 2nd novel - as appeared on the back page of the UK Guardian's Review section yesterday.

Meanwhile, the author has launched a dedicated website for the novel. Find out all there is to know about Half of a Yellow Sun, read an excerpt - and post your Biafra story, if you have one.

• The website maintained by Daria Tunca - remains the most comprehensive online resource on Adichie, and is well worth a visit.
