God’s Playbook by Kevin O. Kruise, Kimberly Kruise Thompson, Paperback

In monotheistic belief systems, God is usually viewed as the supreme being, creator, and principal object of faith. In polytheistic belief systems, a god is "a spirit or being believed to have created, or for controlling some part of the universe or life, for which such a deity is often worshipped". Belief in the existence of at least one god is called theism.

Conceptions of God vary considerably. Many notable theologians and philosophers have developed arguments for and against the existence of God. Atheism rejects the belief in any deity. Agnosticism is the belief that the existence of God is unknown or unknowable. Some theists view knowledge concerning God as derived from faith. God is often conceived as the greatest entity in existence. God is often believed to be the cause of all things and so is seen as the creator, sustainer, and ruler of the universe. God is often thought of as incorporeal and independent of the material creation, while pantheism holds that God is the universe itself. God is sometimes seen as omnibenevolent, while deism holds that God is not involved with humanity apart from creation.

Some traditions attach spiritual significance to maintaining some form of relationship with God, often involving acts such as worship and prayer, and see God as the source of all moral obligation. God is sometimes described without reference to gender, while others use terminology that is gender-specific. God is referred to by different names depending on the language and cultural tradition, sometimes with different titles of God used in reference to God's various attributes.

Kevin () is the anglicized form of the Irish masculine given name Caoimhín (Irish pronunciation: [ˈkiːvʲiːnʲ]; Middle Irish: Caoimhghín [ˈkəiṽʲʝiːnʲ]; Old Irish: Cóemgein [ˈkoiṽʲɣʲinʲ]; Latinized as Coemgenus). It is composed of caomh "dear; noble"; Old Irish cóem and -gin ("birth"; Old Irish gein).

The variant Kevan is anglicised from Caoimheán, an Irish diminutive form. The feminine version of the name is Caoimhe (anglicised as Keeva or Kweeva).

O, or o, is the fifteenth letter and the fourth vowel letter of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is o (pronounced ), plural oes.

A paperback (softcover, softback) book is one with a thick paper or paperboard cover, and often held together with glue rather than stitches or staples. In contrast, hardback (hardcover) books are bound with cardboard covered with cloth, leather, paper, or plastic.

Inexpensive books bound in paper have existed since at least the 19th century in such forms as pamphlets, yellowbacks, dime novels, and airport novels. Modern paperbacks can be differentiated from one another by size. In the United States, there are "mass-market paperbacks" and larger, more durable "trade paperbacks". In the United Kingdom, there are A-format, B-format, and the largest C-format sizes.

Paperback editions of books are issued when a publisher decides to release a book in a low-cost format. Lower-quality paper, glued (rather than stapled or sewn) bindings, and the lack of a hard cover may contribute to the lower cost of paperbacks. In the early days of modern paperbacks, the 1930s and 1940s, they were sold as a cheaper, less permanent, and more convenient alternative to traditional hardcover books, as the name of the first American paperback publisher, Pocket Books, indicates. In addition, the Pocket Books edition of Wuthering Heights, one of the first ten books it published in 1939, emphasized the impermanence of paperbacks by telling readers if you "enjoyed it so much you may wish to own it in a more permanent edition", they could return the 25 cent book to Pocket Books with an additional 70 cents and it would send them a copy of the 95 cent Modern Library edition "substantially bound in durable cloth."

Since the mid-20th century, paperbacks can also be the preferred medium when a book is not expected to be a major seller and the publisher wishes to release the book without a large investment. Examples include many novels and newer editions or reprintings of older books.

Because paperbacks tend to have smaller profit margins, many publishers try to balance the profit to be made by selling fewer hardcovers against the potential profit to be made by selling more paperbacks with a smaller profit per unit. First editions of many modern books, especially genre fiction, are issued in paperback. Best-selling books, on the other hand, may maintain sales in hardcover for an extended period to reap the greater profits that the hardcovers provide.

S, or for lowercase, s, is the nineteenth letter of the Latin alphabet, used in the English alphabet, the alphabets of other western European languages and other latin alphabets worldwide. Its name in English is ess (pronounced ), plural esses.
