Sharper than a claw and more stunning than a phaser blast, The Book of Grudge's Prime Directive features her take on everything from space travel to the proper care and training of an array of alien species, STAR TREK-inspired quotes, and haiku meditations on Grudge's most favorite things, including napping and people (as long as they're far enough away).

Make no mistake, Cleveland Booker's massive - and massively cool - cat, Grudge is no mundane mouser. This taciturn tabby is, in fact, "a Queen." She knows it, and everyone aboard the Discovery knows it, too... though some realize it just a bit too late!
