HELP! Need YA Lit title suggestions

I’m working on the professional development workshop that I’m giving to middle and high school teachers later this month on using Young Adult Literature across the curriculum. I’m looking for title suggestions – anything that might fit the following categories:
– content area related books (science, math, social studies, foreign language, art, phys. ed. etc)
– important topic/current issue books – ex. the economy, government, war, genocide etc.
– books that would compliment classic texts that are often taught in school (something to compliment Catcher in the Rye or The Crucible etc.)
– any books that you think are “must reads” for either teenagers or teachers

Please send me any titles you’ve read and enjoyed or even just heard of that you think might fit the bill for this workshop. If you know of good places to research titles, I’d love that information as well.
Thanks! I’ll be happy to share my workshop materials with anyone interested – just let me know.
