I liked Algorithms by Dasgupta-Papadimitriou-Vazirani http://algorithmics.lsi.upc.edu/docs/Dasgupta-Papadimitriou-Vazirani.pdf http://algorithmics.lsi.upc.edu/docs/Dasgupta-Papadimitriou-... It's written in an approachable, almost conversational style. Beyond that, for a broader view of algorithms and computing that includes AI, there's Artificial Intelligence: A Modern Approach by Russell/Norvig. My favorite part of that book is actually the "Foundations of Artificial Intelligence" which goes into the deep history of computation (as far back as ancient and medieval times).
