There are a lot of good books, but based on your description, I think the best book is Middle Limit Hold 'em Poker by Ciaffone and Brier. They take you through every phase of the game, from pre-flop to the river, with numerous sample hands that are explained step by step.
It will take your limit hold 'em game to another level.
