Friendship in one click. Stone T.

Halhi 12 years, she studies at school, loves to hang out with friends, and also... writes programs! In the summer camp, she created an application that helps to make friends - what could be better? All her classmates from the new social network are simply delighted - and now from Ally herself too!

But what if the unverified application gives an error? What if, due to this mistake, instead of new friends, enemies will turn out? And what if Allya can now help only the one whom she was the last to add as a friend?
