Examples

// list everything
def results = Book.list()

// list 10 results def results = Book.list(max: 10)

// list 10 results, offset by 100 def results = Book.list(max: 10, offset: 100)

// list 10 results, offset by 100, orderd by title in descending order def results = Book.list(max: 10, offset: 100, sort: "title", order: "desc")

// list all books, eagerly fetching the authors association def results = Book.list(fetch: [authors: "eager"])

When max is specified as a named argument this will return a api:grails.orm.PagedResultList which has a getTotalCount() method to return the total number of matching records for pagination. Two queries are still run, but they're run for you and the results and total count are combined in the PagedResultList.
