The Program by Suzanne Young

Teenage suicide has become an international epidemic, ending in the death of one out of every three teens in the United States, and as a result a few larger cities have been trying out a new solution to end the killing. Even London is moving towards instating the Program.

The Program is a place that teens can go to be cured of all of the things that cause them to be upset, distraught, depressed, and desperate to end their lives. When teens go into the Program, they are in a very bad place, and when they come out they are calm and peaceful - and they remember almost nothing of their life "before." 

Sloane, her boyfriend, and their friends are terrified of the Program, knowing that it leaves the cured as blank versions of themselves. So they hide their grief (because all life is a natural balance of joys and pains) as best they can, but when the Program starts to come after those they love, they might not have the power to stop it. 

Sloane narrates this story, and being able to see all sides of the program is a special treat. Readers will root for the characters every step of the way, through their love, their hurt, and their love again. The worst thing about this story is that the sequel, The Treatment, isn't scheduled to be due out until 2014! :)
