Give introduction on bioinformatics for a computer scientist

Question

Problem:

Question: Do you have any suggestions on a suitable introductory text on bioinformatics for a computer scientist?

Any recommendations with pros and cons of different books would be appreciated. I'm mainly looking for a brief introduction since I'm a novice to this field.

I found some books like

1. Systems Biology by Edda Klipp,
2. Introduction to Bioinformatics by Arthur Lesk
3. Bioinformatics For Dummies
4. Bioinformatics and Functional Genomics by Jonathan Pevsner
5. An Introduction to Bioinformatics Algorithms by Neil C. Jones and Pavel A. Pevzner

I would like to develop software related to sequencing application.

Any ideas? Or better yet, pointers to places where this has already been answered?
