At first, this Irish and Australian pair did not give me a great first impression. Don't worry, I'll change my mind about the book. But if you're like me, you also may be put off at the start for their premise that informed their book title: Eutychus.
I don't believe Eutychus died by being bored of Paul's preaching in Acts. This is the thing they say they're trying to save preachers from. It may be true that Paul's preaching wasn't the greatest. I'm not sure. Some texts seem to show that he wasn't very engaging, but his preaching was deep and that's what they wanted.
Aside from my initial quibble with the authors over their hermeneutic on Eutychus, this is a good book. I was skeptical, sadly, so the first chapter or two was not read with near enough depth. But this book speaks to the dynamics of how to preach in a more entertaining and lively way. This does not mean that pastors should become entertainers. Far from it. But this book is short, practical, and gives a lot of insight for how to make the sermon a much more enjoyable listen for those who sit under the teaching that has been prepared for them.
If you want a book on preaching structure, I recommend other books like Ramesh Richard's Preparing Expository Sermons. If you want a generally well rounded preaching book, Bryan Chapell's Christ Centered Preaching is the book for you. If you want preaching books that show the importance of God's presence in preaching and the task a preacher has in displaying that, Darryl Johnson's The Glory of Preaching is a magnificent work. If you want a book on a pastor's character, I cannot recommend Rick Reed's The Heart of the Preacher enough. This book, however, is for how to speak to others and to remember the joy of preaching as a privilege and delight. God's word should enliven a preacher, as it should the congregation the pastor preaches to. If you're looking for an appropriately fun read about a rightfully serious topic, this one is most certainly a book I can recommend.
