Sincerely, Cleo.

Cleo always thought monsters looked like monsters.

She was wrong.

One message.
One stranger.
One black heart scratched into a mirror.

And suddenly, Cleo finds herself tangled in a world of secrets, obsession, revenge, and people who should never be trusted.

Santino knows more than he's telling her.

Cleo knows more than she realizes.

And somewhere between wanting answers and wanting revenge, she becomes something she swore she'd never be.

Because sometimes, the girl you need to save...

is the one you should be afraid of.

Sincerely, Cleo.
