Catfishing On CatNet by Naomi Kritzer

A box drops out of the sky. Steph opens it to find exactly what she needs to alter the sex education robot teacher in her school (the one that will not answer 'controversial' questions). Where did the box come from? Who sent it? It is not the first incident like this recently. It's like someone is following Steph's conversations online.

Steph's only friends are on CatNet, a social media site dedicated to cat pictures. She never has a chance to make friends at school because her mother makes them move every few months. Why you may ask? Because Steph's father tried to kill both of them in a house fire when she was young. Her online friends do not know what Steph looks like or where she lives because her mother forbids her to give out any personal info that could give away their location.

That might sound a little paranoid except that Steph's father is a computer expert, so keeping a low profile is best. Her mom is, too; she makes money by doing jobs remotely for an old friend.

Now about that mystery box: it turns out that CatNet is run by an AI, a sentient computer program who decides they want to help people and Steph in particular. Imagine a being following all your online activity - scary? Maybe, but this being can also track your father and hamper his search for you.

Steph is a really great character with good friends (including her new in person friend, Rachel) who support each other. There are lots of unanswered questions in her life that make for a suspenseful story.
