Pretty Shore (Astonvale #2)
Carla Caruso

But despite Celeste's penchant for organisation, things have a way of veering off-script. She soon discovers the last person who occupied Sabine's pad - the designer's model daughter, Romy - died from a possible overdose. Plus, Sabine's uber-glam real estate agent seems intent on throwing herself at Lenny. Meanwhile, Flip is distracted by the bad-boy son of a rock star, Blaise Zenith, who some say is responsible for Romy going off the rails.
And Celeste thought sunburn and sand in the house were all she'd have to worry about these holidays.
