After the monsters raised from Mt. Ebbot they quickly declared peace. They coexist and lived with humans, for a single moment everything was perfect... but then that moment changed. The ambassador of monsters became ill, the greedy humans saw this as a chance to attack. No one can really pinpoint who made the first strike, but that did not matter for war was inevitable. Humans died. Monsters died. Me, however, my story was just beginning. [Cover: http://weheartit.com/entry/group/95418338] [I own none of the artwork within the chapters]

Alone in a condemned world where monsters and humans fight for power constantly, Y/N survives off of the wood's riches and the small scraps of shelter she can find in ghost towns. Allies and friends have come and gone during the war, either killed or have parted ways. It's not all that bad. She could be dead, after all. One afternoon when shipments from the Human Capital come on a train, she meets a mysterious stranger who saves her life. He's a monster, no doubt, a skeleton to be exact. Y/N is intrigued by the monster and decides to follow him into the next town over where he disappears into an abandoned warehouse. Y/N follows him in only to be pinned to the wall for questioning. After answering all his questions, introductions are made and Y/N learns that the skeleton's name is G. Y/N likes G despite his hateful nature and somehow convinces him to let her come along on a quest he's taking to save his brother from the Monster Capital where they took him for war. After surviving assaults, the government, and Mother Nature herself, Y/N and G start to form a special bond that neither of them wants to break. But when everything goes wrong and neither of them is strong enough to prevent it, Y/N finds that the capitals that she had always hated are far more sinister than she could've ever imagined.

This story will contains things such as ABUSE, CAPTIVATION, VIOLENCE, ect. This is the only warning I will give, so if it's not your cup of tea- sorry about that! . . . Death. War. Violence. A world torn apart by two separate races. In a place like that, can peace even exist? Will you fight for your freedom as a human? Or lose yourself in the arms of a monster? . . .

*Discontinued* This is the original version of Can You Hear Me? in it's unedited form. Monsters were back on the surface! But not everyone was happy with the change... though you aren't one of those people! Happy as a (relatively) popular singer, you were oblivious to the growing discontent. That is, until you met Mettaton's friends! The eventful evening changes your life in more way then one, but where you'll end up you don't know just yet. P.S. I do not own Undertale! If I had to give this story an age rating I'd say maybe 14+ or PG 13 I do use swearwords, there is violence, and there may be topics some people aren't as comfortable with. Of course nothing is stopping you from reading, just do so at your own discretion and know I've given you fair warning.

THIS IS A SEQUEL BOOK!!! IF YOU HAVE NOT READ THE FIRST BOOK YET THEN GO FIND IT ON MY PROFILE!!! Anyway, now for the summary: After death, you hadn't expected much to happen. You fell immediately into a place like the void. You just wanted to reconcile for what you'd caused, but your heart had a wish of its own. You wished to turn back the clock and set things right. You wanted to make everyone forget your existence and make them happy again, even if it left you alone. Well, you're one of the lucky ones. You're wish came true and you reset time. But not everything went to plan.

Highest Rank: #290 in Fanfiction ××× "Its a mad, mad, world out there, girlie. And your kind just makes it madder." Everyone has a lock. Some people are lucky enough to find someone who holds the key. Opal's lock has been rusted and unused for years. But when a bipolar skeleton wipes away the dust and doesn't mind the rust on her edges, she can tell she's in for one hell of a ride. ××× "That star looks like you." He said randomly, guiding your hand to see the star he was looking at. "How the hell is a star supposed to look like me?" You said, leaning your head on his shoulder. He ignored your sarcastic response and mumbled quietly to himself, "It's the brightest one of all." ×××
