Saul is always drawn to water, but his father hates him going near it.

Three years ago Saul's mother walked out to sea and drowned, so now Saul's dad and step mum have taken him as far away from the sea as possible.

Saul feels like he is suffocating and runs away to be near the sea again.

He takes with him his mum's old fur coat, which his father stole, and heads off to the sea, where he discovers his true heritage, that his mother is a selkie, and hasn't drowned after all.
