(Lower) Limit Holdem Books?

[Gauge]

Ive read through the posts and used the search.. Im sure this has been asked before but what is a strongly recommended read for improving my Limit game..

Ive been playing NLHE for about 2 years with reasonable success and occasionally Ill sit at a Limit game when the wait is less and I'm baffled at some of the hands I see turned over. I realize this is most likely a hole in my game not necessarily theirs.

Ill continue to read through the Limit forums and pick things up here and there but a good recommendation would be appreciated.
