A good book for IPSec beginners and refreshers

Before reading this book I think it is good if you have a basic understanding of IPSec topics and terms. In any case, the book explains quite well the basic principles of IPSec and the associated things such as hashing and encryption algorithms (doesn't go too much into details on these ones though...)
The chapter where I lost the thread was ISAKMP and IKE.
Maybe it's me, but I think this was pretty confusing way of explaining it.
Although most likely not the only book I would read about IPSec - it is certainly a good book as introduction into IPSec and many things are explained very well which I didn't find in some other books.
