This is the second book in the series and picks up where the last one left off. The 4 friends are still being stalked by the mysterious A, who threatens to share all their secrets. They suspect that it's this boy Toby who knew that Alison was responsible for blinding his sister with a firecracker. In the end we realize that it wasn't him, so that could only mean that A is still out there.
This one wasn't as good as the first. Maybe if there wasn't so much product placement and these darn girls would just come clean with one another. Makes me glad I don't have any deep, dark secrets. They cause to much stress.
