Don Tillman is socially inept and takes everything in life very literally. An attractive man – a professor of genetics who looks like Gregory Peck – he hadn't been short of female attention but when he decided to find a life partner, he designed a questionnaire listing his demanding criteria.

We meet him now, married to Rosie – she is everything he had been intending to avoid yet she’s intelligent and intriguing. They're living in New York, still acclimatising to their life together when Rosie announces she's pregnant.

This isn't something Don had scheduled but he seeks to tackle it as he does all other developments in his life – with a spreadsheet.

Don receives advice from a variety of sources and isn't able to filter out the good from the bad. The inevitable scrapes and misunderstandings result. The reader can often see these coming but Don's lack of embarrassment and his ability to extricate himself from difficult situations through persuasive argument means we can enjoy it all without cringing or reservation. And he's such a great character that we are on his side, not laughing at him.

But the changes affecting Rosie, biologically and emotionally, mean that she can no longer delight in Don's unique approach to life. Does this mean that the Rosie Project will be concluded and Don will once again be alone?

This is a great book with all the charm, humour and originality of 'The Rosie Project' with the added pleasure of allowing us to get to know Don and Rosie better.
