Clean Code and The Pragmatic Programmer are both great books, but really your team needs to be doing code review on every line of code that is going to make it to production. It doesn't have to be /you/ reviewing all of it. As a bonus, having your team review each other's code builds more familiarity with the app(s) you are working on and allows all your team to learn from each other.
