"George is a middle-management, middle-class, middle-aged guy who hates his job and struggles to stay connected to his wife and teenage children. Most guys might end up with a steamy affair and a flashy car for their midlife crisis, but George gets a quirky, philosophical physics professor named Shiloh. Trapped with this mysterious misfit on his morning commuter train, George is dragged into awkward conversations about love, fear, music, and the meaning of life. Shiloh asks George to beta-test an app he wrote for the new Apple Watch--and with a free watch included, how could he say no? When tragedy strikes, throwing George out of his uncomfortable comfort zone, he learns that Shiloh's app lets him journey through alternate versions of his past. As challenges mount in his own reality, George must make a decision that will change him--and possibly the entire multiverse--forever."--Page 4 of cover.
