The best way to start a summary is to say the name of the author and the title of the work and to give the main point of the article. Here are some examples:
1. The complete guide to gardening not only annuals but also perennials and flowering bushes is "Texas Flowerbeds" by Neil Sperry.
2. In "How to Get the Best Gas Mileage," James Stevens explains the importance of car maintenance as well as driving tricks that can save on fuel use.
3. "Organizing for Non-Experts" is Joan Causeways humorous instruction manual for helping messy people get a better handle on their stuff.
Notice that even in these very short summary statements, you can use words like "humorous" to talk about tone. Moreover, you should also notice that you don't have to start with the name of the author and title. That can be placed at the beginning, middle, or end of the sentence.
