The Two Faces of Adam — Carolyn Meyer

In this, the 4th book in the Hotline series, Lan Nguyen wants to do the right thing. He has no doubts about where he stands on drugs. Drugs are bad, people who use them are fools, people who sell them are criminals. Then the high school hotline starts getting more and more drug-related calls, and Lan finds that it isn’t quite that simple.Drugs aren’t Lan’s only worry. His sister and nephew need a safe home, and Lan is determined to provide it any way he can. He’s already working two jobs outside of his regular school hours. And then there’s the viola given him by his friend Lissa, before she killed herself. Can he afford to keep it? And what about April; sometimes it seems she’s ready to give up on him. Is he going to be able to keep it all together—and do the right thing?
