I recently found Shoups book. It's really geared towards an
introductory level text.

A free copy is on the web in PDF format at

Also "Handbook of Applied cryptography", HAC, is a good reading for
more traditional crypto [it doesn't cover ECC though].

"The Guide to ECC cryptography" is decent too.
