Everyone tells Kat that her online personality - confident, funny, opinionated - isn't her true self. Kat knows otherwise. The internet is her only way to cope with a bad day, chat with friends who get all her references, make someone laugh. But when she becomes the target of an alt-right trolling campaign, she feels she has no option but to Escape, Quit, Disappear.

With her social media shut down, her website erased, her entire online identity void, Kat feels she has cut away her very core: without her virtual self, who is she?

She brought it on herself. Or so Wesley keeps telling himself as he dismantles Kat's world from across the classroom. It's different, seeing one of his victims in real life and not inside a computer screen - but he's in too far to back out now.

As soon as Kat disappears online, her physical body begins to fade and while everybody else forgets that she exists, Wesley realises he is the only one left who remembers her. Overcome by remorse for what he has done, Wesley resolves to stop her disappearing completely. It might just be the only way to save himself.

All the Lonely People is a timely story about online culture - both good and bad - that explores the experience of loneliness in a connected world, and the power of kindness and empathy over hatred.
