Lisa Darling - high-flying TV-exec and twice-divorced mother-of-two - has enough on her plate without having to deal with the handsome New Yorker parachuted in to her best friend's job at work.

She's already navigating life with a grotty teenage son, organising a PTA cheese & wine event, supporting her oldest friend through breast cancer treatment and, since she hit 47, facing a new perimenopause symptom every day.

So when Lisa starts feeling overheated every time she clashes with Zach Russo, she convinces herself it will pass. Maybe her HRT just needs adjusting. Until, that is, she finds herself in a sexy - and seriously ill-advised - clinch with him. And then another...

All of which leads to one question: these long-forgotten feelings couldn't be caused by something else entirely... could they?

The beauty and the geek, Lucy and Henry have been inseparable best friends for 20 years until glamorous Lucy decides that Henry, with his penchant for jumpers and NHS specs, is in need of a makeover. But nothing can prepare them for the surprise results! Before long Lucy realises that their lives will never be the same again.
