The Confessional by J.L. Powers
I really liked this tale from El Paso, Texas. Powers follows six teens with various backgrounds a year after an incident where someone blows up a bridge where lots of bystanders are killed. The Mexican population still wants to celebrate Cinco de Mayo, while many of the Americans do not.
After some fights at one of the city's Catholic schools and then the murder of one of the involved students, tension in the city is incredibly high. The six teens all have problems and different view points. I saw this had a terrible review in VOYA, but I thought it was gripping and cool. YAY.
