The Burnout - Grand Format

Sasha is well and truly over it all : work (all-consuming), friendships (on the back burner), sex-life (non-existent). Armed with good intentions to cleanse and relax, she heads to the Devon resort she loved as a child. But it's off-season, the hotel is falling apart and she has to share the beach with a grumpy, stressed-out guy called Finn. How can she commune with nature when he's sitting on a rock, watching her suspiciously ? But when curious messages start appearing on the beach, Sasha and Finn are forced to begin talking - about everything.
What's the mystery ? Why are they both burned out ? And what exactly is "manifesting" anyway ? They might discover that they have more in common than they think...
