Seniors, your summer reading is listed in the Senior Thesis Handbook. Please note that there are several thesis workdays throughout the summer to help you. I strongly encourage you to take advantage of these. They will make your senior year much easier.
Juniors, here is the list for AP Language and Composition, and here is the list for English III Honors.
AP students, I recommend that you start Thank You for Arguing early and read a few chapters at a time, which will give you plenty of time to finish before we return in August. You will likely want to start your book of choice around July. Both books should be fresh on your mind when return.
Sophomores, I also recommend that you start How to Read Literature like a Professor sooner in the summer and read a few chapters a time. Start your book of choice later so that both books are finished close to the beginning of the school year.
For both How to Read Literature like a Professor and Thank You for Arguing, try to get the most recent edition of the book. However, if you have free access to an old edition, the differences are not big enough to warrant spending extra money.
