And will she finally figure out the secret her mother was hinting at before she died?

This will be my first book so please no hate. I am trying to make the book for both genders so if I wrote something for a specific gender please tell me. If you dont like the book than don't complain and just leave. My English is not the best so be ready for ALOT of spelling mistakes. The updates might be slow and will come ... whenever I have time. Do NOT copy my book, you can do it, but i dont think you want to be on my bad side. So now go to the story and see what it holds, I don't want to spoil anything that might happen in It.

Congratulations! You are an average, hardworking individual with a good job and good friends. You're forgetful when taking your medication and could really use someone to take care of you. For some reason you have decided to adopt a bitty. What is a bitty one may ask? A bitty is a small miniature version of some monsters that were created by a huge influx of magic that came bouncing back and shrunk down some monsters after the barrier was broken. They need a lot of care and devotion just like any companion. This is your adventure with you and your bitty.

(I want to point out RIGHT HERE that this is NOT a Reader-Insert. I'm just to preoccupied to fix the description here, and don't want to rewrite the official first chapter again. Chances are once I start focusing all my time into the finale that I will bother changing the description.) You were planning on getting a Bitty, and had ordered some stuff for the little guy. Being the completely normal person that you were, you hung out by a gas station in the rain. You had stopped for a shake after your lessons and you needed a snack. Right before you call it quits, a person carrying a fairly large box sees you and shoves the box into your arms. Before you ask the person what it was inside, they vanish. Now it was just you and the box outside the lonely station. This is my first Bitty story, so will do what I can. P.S, the cover is not mine, it is made by Poetax Core over on Deviantart. This is also WIP, but am trying to work on it as often as I can. As of 9/11/2019 to 9/12/2019, 8 top-ten spots. That's not very impressive considering I have 25 tags, plus I'm lazy to check everyday. On 1/15/20, 6 top five spots. Your guy's votes count and thanks for the support!

*I DO NOT OWN ANY OF THE BITTYBONES IN THIS BOOK UNLESS SAID OTHERWISE! ALL BITTIES NOT CLAIMED BY ME BELONG TO THEIR RESPECTED OWNERS!* Be prepared for slow updates due to there are a lot of bitties to write scenarios for!
