The Cell Cycle: An Introductionreprinted as Oxford ISBN 0-19-509529-4

Really, you need to read this book. Nowadays nobody can ignore the cell cycle since everything in biology either feeds into the cell cycle, is controlled by the cell cycle, or, in most cases, both. Because the cell cycle is so important, there has been a flood of information about its molecular components, but what this book does is take all that information and place it in context by laying out the overall computational logic of cell cycle control. So, although the book does a great job summarizing the extant data at the time of its writing (which is now a little bit out of date unfortunately), its real value is in providing the conceptual hooks onto which the data can be hung. In this regard, it is still just as effective as it was when it first came out in print, and it is still highly recommended for anyone interested in this subject.
