The other hand by Chris Cleave.

I read this a few weeks ago and loved it. It charts the lives of two women who meet on a beach in Nigeria and how that faithful day marks a turning point in both their lives. Skipping ahead the story picks up as one of the women now seeking asylum in Britain looks to track down the other, an English woman working as the editor of a glossy monthly magazine. The story is incredible and seeing as the highlight of the book is how it unfolds I won't go into detail but needless to say it's an excellent read. Beautifully written it paints a vivid and heartbreaking portrait of the lives of asylum seekers and the constant battle they face to find a place to call their own. The words just seem to flow off the page and I flew through the book in just two days and for every page of that I was gripped. Highly recommended.
