I too recommend "A Guide to the Good Life" but saying its a "more complete look into Stoicism" seems a little exagerating. Irvine covers a lot of of the major topics and offers a many excellent ways of integrating them into modern life but underplays one of the most important aspects of Stoicism: living a virtuous lifestyle. He instead heavily plays up the tranquility aspects which I find a bit disingenuous. He also neglects many of the metaphysical aspects of Stoicism which, even if you don't believe/agree with them (I certainly don't), makes it more difficult to understand the background of a lot of Stoic teachings and practices.

It's best to take Irvine's book as a guide to his own modern philosophy heavily based off Stoicism. Take that as you will, but I would recommend Stoicism and the Art of Happiness and some of the original Stoic classics; Enchiridion by Epictetus (it's short and very direct) and Seneca the Youngers Letters.
