Mythology by Edith Hamilton was absolutely dreadful. Some of the myths were rather interesting, but that was balanced out by them COMPLETELY skipping over the exciting parts. It'd be all "The gypsy told the hero he had to slay a dragon to save her. When he'd slain the dragon...", not even mentioning what could be interesting.
And the Families section, ugh. "A married B, who bore three children, C, D, and E. D married F, who gave birth to G, H, I, and J. I and J were killed, but G lived a long life and married K." for like thirty pages. I feel asleep many times.
Also, I liked Lord of the Flies and To Kill a Mockingbird. Yes, they're required reading, but I enjoyed both of them.
