I'm going to nominate three books which came in second last year, and were therefore considered for January as well. Clearly, these books are appealling because they would not have finished in second place if no one was interested in them.

Pitching in a Pinch by Christy Mathewson
Considered one of the best sports books ever written, and I imagine that summer is the best time to read it because it is about baseball.

Now I'm going to diverge a little bit for my third nomination. Tom's nomination which finished second was the 17th Perry Mason book. I would like to go back to much earlier in the series and nominate Perry Mason #2, simply because it is so early.
The Case of the Sulky Girl - Erle Stanley Gardner
