The Serial Dieter by Rachel Cavanagh

31 Dishes in 31 Days
Following on a year later from the end of ‘The Serial Dater’ where Northampton-based technology journalist Isobel McFarlane had to date thirty-one men in thirty-one days, her health and beauty colleague, Donna Evans, is given the task of trying thirty-one under five hundred calorie dishes in thirty-one days and writing about it.

To add a complication, she has to cover her equivalent (Veronica) at their sister newspaper offices at Hemel Hempstead, Hertfordshire, England, while staying nearby with her exuberant mother, Lesley, at her house in Tring, during the week.
On Donna’s first day she meets James, a married hottie who she can’t get out of her mind.
Is the whole project a recipe for disaster or a sweet success?
