"Sudoku is primarily a logic puzzle, requiring you to discover the correct arrangement of the numbers 1 to 9 in interlocking rows and columns. Kakuro, by contrast, is a number crossword puzzle, with all the clues in the grid; combinations of numbers, called 'Kakuro blocks, ' will help you solve them"--Back cover.

Giant monsters whose every roar and footstep shakes the earth, whose simple stroll through a city wreaks havoc: KAIJU! And even though humankind has never really seen such monsters - we tremble at the thought of them and love to shiver as their screen versions make mayhem: the beast from twenty-thousand fathoms, Godzilla demolishing Tokyo, the massive creature in Cloverfield destroying New York, all of Earth warring with the colossal monsters in Pacific Rim. Now, for the first time, a definitive anthology that gathers a wide range of larger-than-life short fiction with creatures that run a gargantuan gamut: the stealthy gabbleduck of Neal Asher's Polity universe; Gary McMahon's huge sea-born terror; An Owomoyela 's incredibly tall alien invaders; Frank Wu's city-razing, eighty-foot-high, fire-breathing lizard; Lavie Tidhar's titanic ship-devouring monstrosity; a really big Midwest US smackdown related by Jeremiah Tolbert . . . and many more mega-monster stories to feed your need for killer kaiju! With an introduction by Robert Hood, co-editor of the groundbreaking, Ditmar Award-winning Daikaiju: Giant Monster Tales and host of Undead Backbrain, the premier website for matters relating to giant monsters.
