I read to my boys well into high school, one of my greatest parenting pleasures. Towards the end of his senior year in high school, my oldest asked me to re-read the entire Harry Potter series to them, sort of a last hurrah before college.
Some suggestions (some of these might seem like younger kids' books, but they are terrific stories and my 10-13 y.o. boys loved them. My kids also liked stories with male and female protagonists pretty equally):
Cheaper by the Dozen
The Four Storey Mistake and sequel Then There Were Five (I think these are our family favorites)
Roll of Thunder, Hear My Cry (truly a great American novel)
The Kid from Tomkinsville (if your kids like baseball)
My Side of the Mountain
Hatchet
Harriet the Spy
When You Reach Me
Holes
