Describe the book briefly for your readers. The book's title can be a little window into the world your book creates. Whether you write a book title like Tundra or Desert, because the book takes place in a desert, or you choose a title like Oasis, the title should say something about the story, its characters or its setting.
Capture the reader's attention. Whether it is a one work title, or you write a book title that incorporates the entire scope of your book in a one or two phrases, the title should be alluring and intriguing to those who may come across your book.
Brainstorm about your book's theme or plot. You wrote the book, so as you write the title to the book you can look into your heart and the words and find what you think the prevailing theme of the book is. That may turn out to be a great title.
Ask a close friend or associate who has read your book. Tapping into someone else's brain may help you find the best title for your book. As you ask for editing help or proofreading, just ask them to keep thinking of titles in the back of their minds.
Be clever when you write the title to your book. Using a play on words or puns in your title may be completely appropriate for the subject matter. If you have a book written in a humorous style or a fun and kitschy manner, then a cutesy pun is perfect.
