What a fabulously entertaining story about a boy who has to save Earth from annihilation. There's plenty of action, funny moments, and terrifying situations. The world is highly detailed and the writing verging on poetic at times. The characters get under your skin: you'll love them or hate them. Even the villains, however, have moments where you'll sympathize with them. Billy is a reluctant hero, but accepts his role and thinks of the perfect solution to destroying his foe. (You'll have to read the story to see if he succeeds.) Sal is a vivacious and funny alien. She quite often steal the show. And Typhon is a dastardly evil villain. My biggest complaint is the cover of a boy asleep on the ground (on Amazon) doesn't do the story justice. It looks more like a thriller or mystery, and not the sci-fi adventure that it is. (The cover of the black hole here is so much better.)
