Your son will enjoy his new freedom, which can include freedom from draconian group punishments and freedom from depressing, boring (to boys) female-centric YA lit
In case this is helpful: I developed DS11's reading list after looking at the curriculum and summer reading lists of our local upper crust private boys' school. The books are much more male-friendly and accessible.
Another idea: make the lit more meaningful by tying it in with social studies/history. For example, read an age appropriate version of Gilgamesh while studying ancient civ. Now that's a story a boy can love. Friendship, battles, a hero's journey. For WWII try The Art of Keeping Cool and Code Talker instead of the usual fare.
Find some excellent local resources: homeschool groups (inclusive groups are usually more academically oriented), science centers, parks and recreation offices, and libraries often have activities and classes for HS kids.
Enjoy your journey!
