Roly and Mum must find a new home where seagrass still grows abundant, but the journey promises to be perilous.

A peaceful bay once brimmed with dugongs, but now it's only Roly and his Mum. Pollution has killed all the food, and everyone else has moved away. Starving from the scarce seagrass, Mum tells Roly that soon, when he is old enough, they will set out in search of a haven for dugongs like them where seagrass still thrives. But the journey is perilous, she warns. To survive, he must stay close. Stunning seascape illustrations serve as a reminder of the hidden beauty that we could lose.
