Smithson, L. D.: The Shame Game

All it takes to turn your life upside down is one notification on your phone.

Someone knows what you did, what you spent years trying to forget. Now they're going to make it public. Unless you do exactly what they say.

Once you've followed their instructions to the letter, you realise this is just the start. Because they've led you to a secret that your friend would kill to keep hidden, a story that would ruin them if it ever came out.

Then a new text message arrives:
Welcome to The Shame Game. If you want your secret to stay hidden, you need to tell the world what your friend has done. You need to ruin them?
