I think you mean: Cryptography Engineering : Design Principles and Practical Applications by Niels Ferguson, Bruce Schneier, and Tadayoshi Kohno
The book is introduction to the engineering problems and details when implementing cryptography. It introduces primitives, like symmetric ciphers, hash functions etc. and then shows how to write actual protocols using them. It covers many practical details and implementation concerns. I think it's good read. Just bear in mind that it's not comprehensive or authoritative. Some advice can be controversial. For example, they lean on authentication before encryption that others consider bad practice.
No experience, but I wrote "I hear good things about Cryptography Engineering".
That said, at least one colleague was much happier with Security Engineering (also available for free online, and the non-crypto parts age well). Security Engineering doesn't teach you hard crypto (much), but does teach threat modelling and presents various solutions.
