Evie and Lottie are twin sisters, but they couldn't be more different.

Evie's sharp and funny.

Lottie's a day-dreamer.

Evie's the fighter, Lottie's the peace-maker.

What they do have in common is their Jewishness - even though the family isn't religious.

When their mother gets a high-profile job and is targeted by antisemitic trolls on social media, the girls brush it off at first - but then the threats start getting uglier. . .

What We're Scared Ofis a taut thriller, a tale of sibling friendship and rivalry - and a searing look at what happens when you scratch beneath the surface.
