If you do a search on this forum you'll probably find quite a few.
Some of the ones that I've read are
Steve Graham's book which is truly excellent overall,
Bill Brogden's book which covers a lot of different features of Web Services on many platforms, and
James Snell's book which has good coverage of some obscure topics like the details of
SOAP encoding[/URL].
