The Complete Book of Chess Strategy by Silman. Just saw this yesterday for the first time and its the first Chess Book I felt I had to spend the money on. Simple, easy to digest and full of tactics and strategy. I'm already finding myself playing better in just one day as a direct result. I find a lot of the above books to either be to loaded with notation and grand master games to be useful to a beginner, or in the case of Collins' Understanding Chess Openings, to be a bit over the top in his language.
Compare if you will:
The development of White's bishop to c4 prepares castling, eyes the f7-pawn and hinders an early ...d5. We would need a pretty compelling reason not to play such an obviously logical move and unfortunately such abstention is justified by the fact that Black, by most accounts, has a pretty easy route to equality in all variations. Attention has thus moved away from the Italian Game, with its more durable neighbour the Spanish Game (Ruy Lopez) proving a more promising route to an enduring edge for White.

There's just much easier ways to say the same ideas. All he does is make it more confusing.
Compare that with some text from Silman:
While the Caro-Kann (1.e4 c6 2.d4 d5) and the French Defense (1.e4 e6 2.d4 d5) both strive to gain a central foothold with a defended d5-pawn, the Caro leads to calmer positions than its French brother. On the positive side, the move ...c6(instead of ...e6) keeps the c8-h3 diagonal open for Black's light-squared Bishop. The negative side of this opening revolves around the fact that ...c7-c5 is still an important source of counterplay and, as compared to the French, Black has already moved this pawn and lost a tempo as a result. This slight loss of time in playing ...c7-c6 followed by a later ...c6-c5 means that Black will try to slow the play down.

Silman's book is just great in my opinion for beginners because of how clear and easy to use it is.
