‘Comedy gold’ Clare Chambers'Both funny and unexpectedly emotional' Jill Mansell Freaky Friday meets David Nicholls' Us. ***** Last night Paul and Sian called time on their marriage. After dropping their youngest at uni, the thought of sharing a loveless empty nest was just too much. But this morning something else feels wrong. Maybe it's sleeping apart for the first time in twenty-four years. Maybe that second glass of wine hit harder than usual. Maybe this is just what an older body feels like … Except the mirror above the sink betrays a much stranger truth.Inexplicably – impossibly – Paul and Sian appear to have switched bodies. And they're desperate to change back. After all it'll be next to impossible to keep this a secret from troubled kids, needy parents, work colleagues and friends, never mind having to wrangle their new body parts.
