I found Play the Caro-Kann by Houska to be very good.
I need a caro-kann book

Lars Schandorff, especially given your rating. I think Houska's book is good but it is quite limited in some areas (like the advance variation).

Lars Schandorff for sure - I switched completly to caro after reading his book and trying it out. Very easy to play and still lots of attacking ideas.

Lars Schandorffs is the best no question.
