I Don't Know how She Does It by Allison Pearson (Kate Reddy #1)

Meet Kate Reddy, hedge-fund manager, wife and mother of two. Always time-poor, Kate must monitor nine currencies in five time zones but also keep in step with the Teletubbies. Factor in a manipulative nanny, piggish colleagues, a long-suffering husband, her quietly aghast in-laws, two needy children and an email lover, and you have a woman juggling so many things that some day something's going to hit the ground. And that something might just be Kate.
In an uproariously funny and achingly sad novel, Allison Pearson brilliantly dramatises the dilemma of working motherhood at the start of the twenty-first century.
