Suggestions for Summer Physics Reading

[some_letters]

Hello. I've just gotten through my first year of undergraduate physics (not much physics really) and won't have the time to take any courses over the summer. I think it'd be in my best interest to keep my mind on my studies so I figure I will pick up a few books to go through over the summer. I'm wondering whether any of you can recommend others to me. I will be taking mathematical physics and modern physics next semester.

Books so far:
How to think like a Mathematician by Houston
Warped Passages: Unraveling the Mysteries of the Universe's Hidden Dimensions by Lisa Randall

Other than theses, I'll be browsing through the textbooks for next semester and reading some discworld.

I always recommend "The Black Hole War" by Leonard Susskind. Its not a technical book, but a very great read.

I got a few from this thread : https://www.physicsforums.com/showthread.php?t=603598

Others I'd suggest:
Cosmos - Carl Sagan
Men of Mathematics - E.T Bell
6 easy pieces - Feynman
6 not so easy pieces - Feynman
One, two, three...infinity - George Gamow. (I really liked this one)
