You can download a free PDF sample of Faithful to the End: An Introduction to Hebrews Through Revelation by Terry L. Wilder, J. Daryl Charles, and Kendell Easley courtesy of Broadman and Holman. It is the entire chapter on Hebrews and gives you a good idea of what the whole book is like.
I am using Faithful to the End as the textbook for my Jewish Christian Literature class this spring and have enjoyed it so far. While there are not very many books covering this section in survey fashion, this is certainly one of the best. It forms the last part of a NT survey set, with Craig Blomberg covering the Gospels and Acts and Epistles in two separate volumes.
Yeah Blomberg!!!
Every time I say his name in class now I have to smirk a bit because of you and Talo.
