Sister, By Rosamund Lupton

Currently topping the Richard & Judy hit parade, Rosamund Lupton's highly charged domestic thriller centres around the close bond between two highly intuitive sisters.

When New York-based designer, Beatrice, gets a call in the middle of Sunday lunch to say that her younger sister, Tess, has gone missing, she boards the first plane back to London.

Framed as a letter from Beatrice to Tess, the facts of Tess's disappearance and the following investigation into her probable murder are drip-fed to the reader, as are details from their difficult childhood.

Lupton's crisp insights into grief and familial guilt are married to a confidently executed plot. Free from the genre's more mawkish excesses, Lupton's persuasive narrative voice is what keeps this classy debut on track.
