When the waves swallowed them

The first rule of rescue is: Don't add to the number of victims. Grace has just experienced every teacher's worst nightmare. After a demanding day in the Australian wilderness, she stands on the shore of a raging ocean, watching as three of her students are swept out to the open sea by strong currents. During a multi-day excursion into the Australian bush, where secondary school students learn about survival far from civilisation, a group of teenage boys comes up with an idea: they decide to sneak away from the teachers' watchful eyes and go for a swim in the ocean. By the time their teacher, Grace, spots them, they are already far from the shore. As a lifeguard, Grace knows that helping them would mean risking her own life. Should she stay on the shore, or attempt the impossible and almost certainly perish in a battle she is destined to lose?
In the chaos of the following days, Grace must face the grieving parents, and new facts begin to surface. Who put the boys up to this deadly adventure? Who is responsible for their deaths? Who can Grace still trust?
This gripping psychological thriller, set on the Australian coast, is based on the author's personal experience as a secondary school outdoor education instructor and volunteer lifeguard.
