Angie Silverton and her husband are taking a much-needed holiday on the cruise ship Mermaidia, so the last person she hopes to bump into is her one-time best friend Selina and the man Selina stole from her and married twenty years ago.
And what she needs even less is to be marooned in Malaga with Selina when both of them manage to miss boarding the ship in port.
It will take three days for them to travel across Europe to catch up with the ship again in Croatia. And in the company of each other twenty-four/seven, a lot of old baggage is going to be unloaded.
