book recommendation...?

[J.D. Bronson]

I am looking for a good FreeBSD book recomendation
that would over the 5.x series and be available in Barnes/Noble
locally.

(My wife is looking for some gift ideas for me and I felt this might be a 
good start)

I dont need a totally novice book, nor do I need a super-advanced book.

Something that can cover stuff in between and ideas on performance
and security.

Thanks!
